paint question 73 plastic bumper
Ok...... I Have Painted My Bumper Twice Now And Each Time The Paint Cracks. I've Used Flex Primer Andthe Color Coat Still Cracks. I Need To Know If You Have Any Hints To This Madness Or Should I Just Pay Someone To Do It....

You didn't say if the bumper cover was new. If it is old, the cracks may be in the cover itself, and showing up through the paint. If a new cover, cracks shouldn't appear even if no flex added in the color coat.

You need to wet-sand thru the crack, removing any traces or the split paint. Re-seal and shoot color with the appropriate amount of flex additive. We don't add flex to the clear, as urethane clears are fairly flexable when cured.
