I am extremely pleased with the results of the Resistall protectant that I opted to have applied to my new GMC one month ago. I work very long hours and the last thing I want to do is spend my entire day off scrubbing bugs and tar off my car. It is ridiculous to me that people posting here have such negative comments and even suggest having auto detailing done once per year as a replacement. Professional auto detailing is very expensive and purchasing additional "hot wax, etc" through the drive through car washes can add up quickly....not to mention the TIME involved in all of that. All of the extra efforts suggested to substitute the product just seem time consuming. I prefer not to be spending my time excessively on my car. My prior car DID NOT have this applied and regular car washing did not seem to make a good difference. I have run through the cheapest level on automatic car washes three times this past month and my car looks great with no dirt residue after each wash. Before the resistall, this did not happen.
