Painting Plastic Bumper Covers
I am painting may car.
I would prefer to paint the front and rear bumper covers off the car before putting them on.
This is a race car so none of the usually BS constraints are in place. No head lights, fender liners, or any other factors to get in the way.
I put the nose on and aligned it in about 10 min. Rear goes on in 5 min. These times did not include the plastic rivits. All parts will be test fitted prior to final paint and assembly.
If I paint it with flex agent, how long do I have to install it and how much twisting will it take?
Also do I need to prime the bumper cover which is a factory black primer to cover with blue paint. If I do not prime, I would water sand with 400 to 600 grit.
My thought are if I use primer I will have to add flex too and the flex may be flexed out by the time I add color.
Bottom line I do not want the paint to crack when I put the bumper covers back on.

Re: Painting Plastic Bumper Covers
add flex agent to the color. that will keep the paint from cracking. make sure its compatible with the paint though.

Re: Painting Plastic Bumper Covers
My real question is...
How long does the flex agent last? Can I wait a year to put the bumper cover back on?
I was under the impression that the flex agent only lasts a short period of time so parts need to be on the car or installed quickly to minimize the flexing of the part before the flex agent burns off.
