Painting plastic bumpers

[falconvan]

I've got a paint question; We're going to paint my son's 94 Firebird and I'm wondering how to address the plastic nosepiece. There's a lot of cracking in the paint on this part. How do I prep this to paint it so that doesn't come back? Is there any special way to sand these plastic pieces so as not to mess them up? Anything you have to add to the primer and paint for flexing? Our plan is to do as much of the prepwork as possible and then have Macco shoot it.

I use a plastic adhesion promotor on the bumper covers, and you should add a flex agent to the paint when painting bumpers.... If Maaco is going to shoot it, I'd check with them and see what they recomend.

There is a clear product called Bulldog that is a cure-all for plastics. It allows you to use the same paint for best color match. Great adhesion promoter...then it's mixed with each coat of paint so it becomes flexible, and also "cross-links"the layers for max adhesion. I highly recommend it. Just read the instructions carefully and go to work.

Yuppers, the Bulldog stuff is great.... Even the DuPont rep that calls on the shop recomends it....

Thanks HRP, I don't do any of the painting anymore and couldn't remember the name of it!!!! Heck, anymore it's a good day if I remember my name!!!

Sounds like the right stuff; do you mix it with the primer, too?

My guess is, if the paint is cracked you'll have to sand it off.

Tell your kid to quit running into stuff.








Just kidding.

Tell a 16 year old to quit running into stuff? Boy, you dont ask for much, do you?
