painting vent caps

[alacran]

im in the process of having a friend color match my escalade vent caps for me soon too.

Update- so, I started the process of painting my vent caps. Sanded them with 600 grit, washed them and applied adhesion promoter. On the first one, the promoter wrinkled and that's as far as I got on that one. Not sure if it's because I laid it on too thick or because I painted in shade and let it dry in sun( sudden temp change) so I avoided both situations on the second one. Maybe over did it but got 4 light coats of promoter, 4 light coats of paint, and 4 light coats of clear. Funny thing is I shook the clear spray can for about 3 minutes waiting to hear the mixing ball then read the instructions and it said "Note: clear does not contain mixing ball", lol. No wrinkles and looks freakin awesome.I'm pretty impressed with duplicolors color match. I haven't installed it yet but held it up to the tahoe and seemed to be a perfect color match! The worst part was prepping. I'll get pics up when I get them installed.

I got 1 vent cap installed. I still need to sand the other one due to the adhesion promoter wrinkling. Here's the one installed and your inspiration 01tahoenjn. I'll get better pics up when I finish painting and installing the other one.

Thanks Ryan. So, I sanded down the other one and applied adhesion promoter and the dang thing wrinkled on me again. It didn't look too bad so I put on the first coat of paint and it wrinkled even more. Does anybody know why it keeps wrinkling on me? The first cap had no problems at all. What am I doing wrong and do I have to start all over or can I just sand down the wrinkles and continue?

clean clean clean. it seems as if its got some silicone based dressing on it. looks like ur gonna need to sand it down again, clean it with soap and water very thouroughly and re try it. anytime ive had automotive paints wrinkle its been because of silicone based stuff being used in the past. were they "worn" looking like most of them are? the plastic, once worn a bit, tends to absorb more in the porus stuff, even if u cant feel the porousness of it, thats whats making it hazy or oxidzed from the get go....so all that to say, i feel its a cleaning issue, if its even possible to get it cleaned enough. im just worried that if u sand and repaint it as is, its going to continue to have issues later on...

Thanks Chad. I'll be sure to clean thoroughly. Anybody know what will remove that adhesion promoter. I can't get my fingers into the vent holes to sand and thats primarily where the wrinkles are.

When I smoked my tails I used an paint prep/wax grease remover to ensure no oils. i also had wrinkling at first but that was because I was putting the layers on too thick...I would agree with Chad on a cleanliness issue....the color match looks awesome-

Duplicolor has a new clear coat out that isn't the plain old lacquer clear, it's in a smaller can specifically designed for automotive paint and it works great...redid the clear on my wife's lexus headlights (which are roughly the size of a football field) and they came out flawless....the lacquer clear I sprayed my tails with 2 years ago is already chipping.

Thanks Yukon Ron. The automotive clear is what I used and it looks great. So, finally, sanded off all the wrinkling in the holes on passenger side vent cap (what a b!%ch), cleaned, painted, and cleared. Here are the results. In the second pic it looks kinda silver but it's just a weird reflection of the sky. Paint matches very well. I'm very happy with it. What do you guys think?
