View Full Version : People with painted lowers have this problem??

03-20-2007, 08:07 PM
I painted my lowers about a year ago. After going thur winter and normal everyday use. the Black lower door trim that was painted has got what it seems to be clear coat cracks. Is there a way to paint the black trim peices in a way that if i hit them they wont crack. Its more of a string like clear coat scratch. If the trim gets bent in the slightest way thats what happens.

This is what happens when your paint "spiderwebs". Use a different type of clear coat. ie. urethane

or what alot of people do is buy the ECS tuning rubber trim because its more plasticy (is that a word?) and it doesnt bend as much at the OEM rubbers.

Paint is going to crack no matter what you do because the rubber pieces can bend more then the paint can even with the correct additives in it.

There is special adhesive promoter(?) to use on "plastic" pieces.

Yes but it doesnt help. Mine has chipped off a few places also, but its been about 2 years

Mine has held up but has cracked on the tip at the end of the driver door, had it painted nearly 7 years ago.

Yes there is Bulldog adhesive promoter which can be used when spray painting. If you are spraying by gun then you can also use a flex agent in the clear.

ok then i will buy esc tunnings kit for all 4 doors...i think its like $100. Then i will paint then again and hope it holds up better

best think to so is just get the s4 sides (reps r fine) and paint those

Using "Flex" Primer before painting should help with that as well.

plus, the edges by the wheel wells are chipped off now too from ice/snow clumping up on it over the winter. i won't paint my lowers again, i'll just get a new bumper, sideskirts and maybe keep the back lower valance painted since it wouldn't be that hard to touch up every year or so.

that paint should not of pealed off on the back plastic is pretty tricky u need to make sure to get a good mechanical adhesion even if ya have to sand then then prime them it will be all ruff looking in primer then sand that that way you have a strong adhesion that looks like it just pealed off ya prob just scuffed it and painted it and that panel has bumps on it so the paint bridges over it and eventually cracks off

oh yah i totally didn't do it right the first time. *shrug* oh well. i'm gonna eventually get a new bumper, sideskirts and just repaint the rear.
