    I gotcha ya! Some other owners have reported the same problem with the roof trim.

    I haven't had a problem in this regard with my 4/01 Built 2001 Impala LS.

    I hear you bbrowne74, however fact is fact. Carnuba is not good for your car. So if anyone is using it then he or she is harming the car. No one that I know of has ever switched from Zaino to another product but you'll hear very often of people switching from other products to Zaino. Below is why Carnuba is not good for your car:

    Carnauba is a, dark yellow, brittle wax. It has no durability. It also has no high shine. In reality it's actually a dull wax. It is not optically perfect and leaves a film (haze) on the paint finish. If you took two identical colored cars and placed them side by side. The one without carnuba would be the true colour. The other car with carnuba would have a slightly different tint to it.

    What you are seeing with Carnauba is a combination of carnauba wax, polyethylene wax, paraffin wax and the key gloss ingredient SILICONE OIL. Silicone oil is inexpensive, greasy, smear, not durable, but shines like crazy. Just try Pledge furniture polish on your car. Voila same shine. Hmm. Pledge is loaded with silicone oil, so is Armor All tire dressing. Did you ever notice how greasy, smeary and dusty, furniture looks with Pledge on it. How soon does your car get dusty after you polish/wax with your favorite product?????:( When does the gloss start
    to drop???

    Silicone oil is not body shop safe and is a painters worst nightmare. Silicone oil always remains a liquid in a mobile state that can permeate and penetrate paint or metal or fibreglass over a period of time. This can cause the term "fisheye" and make repainting virtually impossible. Any vehicle made of a composite material such as Corvettes, Vipers, and Saturns will suffer silicone damage because the sun will burn into the materials resulting in a non-repaintable finish.

    Now here's the best part. Silicone oil and other oils are an essential ingredient of Carnauba based products. It's the only way to achieve a shine. That's why it's used in all Carnauba based polish/wax. However, it has no durability, does not last and it attracts dust and dirt like a magnet and once dust settles on it, it sticks to it. Dust on paint causes tiny Swirls and Scratches. Also Carnauba is very brittle. It will not stay on the paint surface for any length of time. Most of the time less than 3 weeks....... The sun also effects Carnauba based products. The sunnier and hotter it gets, the faster it deteriorates. Remember wax melts and oils tend to migrate to the surface and evaporate... Sad but true.

    Fact: On a sunny 80 degree day, the surface temperature of black paint will reach 149 degrees and go up to 198 degrees if the ambient temp reaches 90. It doesn't take a rocket scientist to figure out what happens to the wax.

    When designing and formulating a polish. These are just a few of the factors that you want to avoid.
  • Anyone that has roof trim on their 2001 Imapla, Please let me know & what remedy did you take..the dealer is ordering new ones but he said there is no guarantee that they will work better..I am thinking of using some type of adhesive to keep the molding down..Also the repairshop at the dealership said the molding is held in place with 2 sided tape..anyone have knowledge of this..Thanks ..John

    I think he had some roof trim problems as well...
  • night_owl1night_owl1 Posts: 760
    I was noticing that same problem this past weekend. It's the soft plastic trim that runs from the front of the car to the back, right? The front end is under the front windshield weather-strip and the rear is under the rear windshield weather-strip. I was looking at it closely and I think it is held on with double stick foam tape. I am assuming that the heat is causing the tape to release from the car, or is tearing the foam in half.

    I believe that replacing the trim will not solve the problem for the long term, especially if it's the same tape. I am thinking of cleaning up the ends and using 3M emblem adhesive or weather-strip adhesive to stick it down.

    Stockalis2, what color car do you have? I have a black one and I am wondering if that is one of the reasons that the trim is coming up. Added heat absorption vice lighter cars.

    Anyone have a better suggestion?
  • night_owl1night_owl1 Posts: 760
    I didn't notice that any of my interior trim was sagging. If it's plastic-to-plastic, I think I would recommend using 100% silicone calking or adhesive vice a glue to keep the trim in place. The calking is available in clear and can be pulled apart if you need to remove the trim, to replace the headliner, for instance.

    Ok, now you got me worried and I gotta look at my car. =)
  • teoteo Posts: 2,508
    Please let me know if you observe the interior trim sagging at the describe points.

    can anyone tell me what wires to jump to bypass the trunk amp? i have a '01 ss and i've heard it sounds a lot better to bypass the trunk amp and run everything off the one in the dash... thanks.

    Saw the pics of the dude that decided to install a TV set in between the seats of his Impala for his small kid....

    Doesn't that TV set become a potential projectile in case of a sudden stop or a crash?

    Noble cause but kinda dangerous IMO.

    My dealer has the new roof mouldings and they are waiting for me to bring my car over so they can match the paint.
    They have promised me that they will paint the mouldings off the car.
    I am not sure that i want the hassle and may not even have it repaired.
  • b4zb4z Posts: 3,372
    I have been using mother's waxes on my camaro since it was repainted in 1993. I have found their carnuba product to be superior to many of the other waxes i used before then, such as rain dance.
    I have also found it to be long lasting. It is often still beading after 4 months.
    While i don't doubt the success many people have had with zaino, i do feel that carnuba is not harmful to a car. It has been used for decades and still sells well today in the face of so many miracle waxes.
    I am also getting excellent gloss from mother's. While my car doesn't look as good as it did 8 years ago it still has the "wetlook" and has no oxidation.
    I am hoping to try zaino soon, but in the interim i will continue to use mother's products.
    As a footnote i used meguiars cleaner/wax on the impala and am not impressed.
  • b4zb4z Posts: 3,372
    One more thing. Don't use liquid dishwahing soap on your car. It is designed to take grease off of dishes. It will take the wax off your car after just a few washings. Use a liquid soap designed specifically for cars.
  • roderacerroderacer Posts: 311
    I used Dawn when I first got my LS. I wanted to make sure that there were no waxes or other oils on the finish before applying the Zaino.

    I wouldn't recommend using dishwashing soap regularly. But it is good for taking off layers of wax. Just take it easy.

  • night_owl1night_owl1 Posts: 760
    Tomaso7 - Not all carnuba waxes have silicone. I agree that most do and that's how they get a carnuba wax that is easy to apply, easy to remove, and has a great shine. I have a wax that is carnuba-based but with no silicone. I asked for a MSDS to verify. I've used it since I received my car and have not had any problems with it.

    When you say that carnuba is not good for your car, are you referring to the silicone in the wax or the carnuba itself? I was a little unclear on that point.

    bbrown74 - You are right in pointing out that every "study" supporting one position can be countered with another one. The NSX evaluation was pretty good, but could use improvement. Only one trial and one of the tests was subjective (how the surface "felt"). However, just because the source was from a NSX fan doesn't mean the information cannot be used by Impala owners.

    Tomaso may be a Zaino dealer, but it doesn't mean his opinion is invalid. On the contrary, if he thought the product was so good that he wanted to be a dealer, I might give his testimony more credit. Then again, maybe not. Like any other information on the net, testimonials and studies it shouldn't be taken at face value.

    I still have a quarter bottle of wax that I'll use up before moving on to something else. Based on the recommendations of others here and articles like the NSX one, I'll probably try Zaino next. I was not convinced solely by Tomaso's recommendation or the NSX study. However due to number of people extolling it's virtues, I am willing to give it a shot. If I say it's the best thing in the world, should you immediately go out and buy it? Of course not. It's everyone's responsibility to do the research and make a decision for themselves.

    bbrown74, if that was your point in the beginning, can everyone just delete this message. I just felt a need to ramble on.

    Actually, I was thinking the very same thing. A TV/VCR unit is pretty heavy and it looks like it's just resting there. Maybe it's attached to the console or something. I just thought it was a neat project.
  • b4zb4z Posts: 3,372
    Nothing like a "zaino" post to liven things up around here.
  • night_owl1night_owl1 Posts: 760
    I was actually thinking of using a clay bar before doing the whole Zaino thing. A follow up with Dawn wouldn't be a bad idea.
  • night_owl1night_owl1 Posts: 760
    They have to color match your car? Does your existing ones look painted? The trim on my car is pretty soft so I wouldn't think any paint would survive for long.
  • night_owl1night_owl1 Posts: 760
    I am assuming you have a MC vice an Impala. If not, WHEREDIDYOUGETASSIMPALA?!?!

    If you want to attempt the bypass, I did a How-To article on it based on the information from people on this board. Go to:

    and visit the How-To section. You may want to consider pursuing a replacement amp (if you have the 104 unit) from your dealer as a warranty job. I have a 104 amp and am satisfied the way it sounds. If I change out the amp, it will be to install an aftermarket one.

  • b4zb4z Posts: 3,372
    I assumed that the color was in the mouldings, but i guess it would be too hard for GM to stock the many different colors.

    Makes me nervous. Having themmess around with my car.
  • spider717spider717 Posts: 106
    The left stip on ym Navy blue 01 LS is also pulling itself up. I pointed this out when I was getting my amp replaced(BTW thanks guys for all the info). They ordered me a new strip and I'm just waiting for the call to have them put it in. In the meantime I just pulled it above the windshield strip so it's not pulling on it anymore.

    Regarding the replacement of the intermediate steering shaft, is it necesery to remove the dash or is the work done under the hood?
  • mediumfrymediumfry Posts: 239
    Teo, I am the dude that installed the TV in the Impala. I too thought about the issue of the TV becoming a projectile. But actually I was more concerned about it being a nuisance for other reasons (distraction, working loose (walking) as we drive along, etc). Fortunately, the TV fits between the front seats like a wedge and sits quite solidly there. I can provide design details of the stand to anyone who likes it. It works great and is easy to build.

    Anyway, there are many things in cars that can be deadly projectiles, and when folks are on vacation, they often have books, toys, drink bottles or a cooler, etc in the car with them. One cop said at a speech that he had only un-buckled one dead person (meaning all the other persons wearing their seat belts were alive) and that the dead person had been carrying a box of kleenex on the rear package shelf. That box, during a front-end collision, flew forward and broke his neck.
    In a front-end collision, the radio/Onstar interface unit is probably at the most risk of being smashed by the TV.

    Thus, the TV as a projectile is a calculated risk as is most anything in life. I won't say it doesn't present a potential hazard. I will say that TVs in cars are becoming very popular and that it doesn't IMO present undue risk, particularly considering the great benefit it provides.

    Your website is hands-down the best personal site on any subject that I've seen. And it continues to get better. Excellent job.

    Just a question for those having problems with the roof trim peeling from the rear window area; do you generally park outside, or is your car garaged. My '00 is Galaxy Silver, and 90% of the time the car is either in my garage, or in the parking garage at work. So far I haven't noticed any release of the trim, but I don't know if that's due to the color, or the fact that the car is garaged most of the time. Just trying to reduce some variables.

    I noticed the moulding raising up on the right side in the back right after I got my car back in 1999, It doesn't really bother me and it doesn't not stick up that far, it is right before it meets the Black rear window moulding, I figure if I let a Dealer fix it, I will then have them curling up like those old Tuxedo Bibs with too much starch in the old comedy movies and never wanting to stay in place, I just keep an eye on it. The side moulding on my left front fender also looked a bit loose back then,(the little one in front of the door on the fender) I just pushed it the rest of the way into place and it has adhered perfectly. Also I garage and if it has to sit outside I use my Car Cover ALWAYS., Does wonders for the life of the rubber mouldings and paint. Don
  • Nightowl..My Impala LS is silver..the dealership ordered neew molding, but I went ahead and fixed the problem with double sided tape..I cut a small piece and slid it under the molding and it is as good as new,,but I am going to let the dealer repair it with new molding..I had the car about 1 month before this happened..keep in touch ..John
  • I agree with you ..I keep my Impala in the garage but I am afraid to let the dealer fix the problem,,it might end up worse than it the way , Mine is Galaxy Silver also

    I have spent a few $$ on car care products. From everything that I have read, its best to stay away from the pure polly coats, at least in Pa...where we experience the full 4 seasons. The paint will flex and the full polly will not, causing probs < so I have read and been told>...I have used on diff sections of my 00LS..Drk Carmine Red...Meguiar's 3 step . I need the protection of synthetic with nvr garaged...parked next to Philly airport all day. All the above are very good....with the 3M perfect paste me the best results. However, nothing can match Zymol...for a really deep shine, but, since I don't have a show car, I am not going to go bankrupt using their products.
    GM Corp minds...pricing yes...out of sight...also....I think my paint job peel and its soft as hell have looked at a lot on new GM vehicles...their paint..looks crappy compared to Chrysler...and even blah..*Fords*....Lookout in 2003...Dodge IntrepidR/T...V8 etc...I may jump over...if Chevy doesn't do anything......
