I am prepping the bumper for painting. It has some hairline cracks in the paint. I sanded the paint off down to the brown/gray urethane. The cracks extend down into the urethane. So now that the paint is off can I just prime it with epoxy or a filler primer? Or do I gouge out the hairline cracks and fill them with flexible repair material?




In the picture there is a white scratch in the middle of the photo. It is barely visible.

I ground mine down to bare plastic when I did mine, the whole thing,both of them. If there are any cracks anywhere else on it they will just reappear. I used 2 coats of filler primer and a top coat of regular primer after I blocked them out.

The top pic is 80% done cleaned off.

You can use Everflex glazing or other similar products made for flexible bumpers. Just don't use Bondo.

I have some Evercoat Polyester Glazing Putty. Could I use it or should I get some Evercoat Poly-Flex Flexible Polyester Glazing Putty (411)? Is there another brand that is better?

You really need to "V" out the cracks & fill them with a flexible bumper repair product (not glazing putty). Once you have them filled & sanded down, prime with epoxy (PPG DP primer) & then if you need it you can smooth it out with the flex glazing putty.
