Hi, when I bought my 05 stang, I remember someone at the dealer mentioning that you should never apply wax to the plastic surfaces (e.g. rear bumper) of clearcoat finished cars?
Is this a true statement or just BS? I don't wax all the time but when I do I use the turtle wax spray on.
"Life should not be a journey to the grave with the intention of arriving safely in an attractive and well-preserved body, but rather to skid in sideways, body thouroughly used up, totally worn out and screaming, holy sh*t, what a ride!"
i never heard that before. i wax my bumpers on my cobra. and did the same on my gt, and all my other stangs. you should use a paste wax every 4-6 months or so. and use the spray wax inbetween the paste coats. i use zymol. works great!

Years ago when I was in high school I remember someone trying to tell my mom the same thing, don't wax the plastic parts, ie. bumpers. We always did anyway, forgot their advice, "blond moments". We never had any problems. So I have heard it, you are not alone. I now am curious to see what others have to say if it is BS or what.
To my knowledge, no coating is applied to plastic surfaces on new vehicles. Additionally, to my knowledge, the painted surface ("clearcoat finish cars") has nothing to do with the treatment of the plastic trim. Ask your local body shop man, and he should tell you that he masks off, or removes the plastic trim before he repaints and clearcoats your vehicle.
There are hundreds of after market detailing supplies that are targeted to your plastic auto parts. I believe there are reasons for that. 1) Plastic is not naturally any one color, coloring is added at the manufacturer. That coloring leaches out, over time, when exposed to sunlight. 2) Plastic surfaces fade, or dull over time, giving the auto an overall dull appearance. 3) Unprotected plastics may "dry out" over time, and crack. Those detailing supplies are attempts to stall, or reverse these deteriorating affects of sun and weather.
Take the time, and see your body man. Then, go see this Ford dealer and see if he'll repeat his statement. I'd love to hear his arguement, we'd love to hear his reasoning for making this statement. There are an awful lot of us that routinely use these petroleum based products on our plastic pieces, with no long term ill affects.

OK to use wax on clearcoat finished plastic?
