Anyone have experience with that coating on your Honda?
I'm inclinded to think it's an overpriced add-on, and that a Honda, already has an excellent finish (with factory applied clearcoat?).
Secondly, I'm inclined to think that if water sits on something, or anything, a water spot can/will form on the topmost exterior layer of a surface, regardless of how many layers are on a surface. Ditto with Pine Tree sap.
The cost is worth it if time waxing/cleaning is factored, but I have a hard time imagining a surface protector which requires little to no maintenance, itself.
