ToplessZ Posted July 27, 2005 Share Posted July 27, 2005 I am wondering if I can just scuff the urethance or plastic with 180-220 grit and paint with epoxy if the urethane bumper and trim is already on the car or do I have to use an adhesion promoter such as bulldog which I already have. Im just scared to use it. Pipe up guys need to get this thing done. Thanks Quote Link to comment Share on other sites More sharing options...
auxilary Posted July 27, 2005 Share Posted July 27, 2005 You can buy urethane impregnated paint to use on flexible components. That's what I painted my airdam with. Quote Link to comment Share on other sites More sharing options...
ToplessZ Posted July 28, 2005 Author Share Posted July 28, 2005 Well Im trying to work with what Ive got. This epoxy primer seems like it sticks to anything like glue and I have a good rough texture for it to bite to. Anyone else used bulldog adhesion promoter? If I can just use the straight epoxy that would be even better. Quote Link to comment Share on other sites More sharing options...
Phyxius Posted July 28, 2005 Share Posted July 28, 2005 every post mentioning paint and urethane that i've ever seen usually indicates that you should use some sort of flex additive to prevent cracking...better safe than sorry in this respect, i would think Quote Link to comment Share on other sites More sharing options...
Vintage-TechZ Posted July 28, 2005 Share Posted July 28, 2005 Hi Jared, If the Urethane part is VERY ridgid.....you can sometimes skip the flex-additive. If it is like the older Z airdams that can easily bend with the push of your hand, use flex as an absolute or the paint will soon crack/fracture most certainly. It doesent require much additive to work correctly. I have found spraying the part in warm (not hot) sunlight for a part like this ,makes the topcoat flow out best with a flat high gloss because of it. The adhesision promoter you have is good insurance as well since most urethane parts weep a waxy release if new and not baked out. If the part is quite old (years) then again you could chance skipping that step as well......but I wouldn't if it were myself doing it. Good Luck.......hope it turns out slick ! ...............Vinny 8) Quote Link to comment Share on other sites More sharing options...
ToplessZ Posted July 28, 2005 Author Share Posted July 28, 2005 ok guys I guess I better admit now that this is for the bumper and door handles on my civic (non rice burner) Im trying to get it painted before I go to college in a couple of weeks. The bumper is not flexy and the door handles of course are not. Ive used other parts such as spoiler etc that come pre primed and Im thinking there was no flex agent added to that? Keep the info coming getting ready to paint in the next day or two. Quote Link to comment Share on other sites More sharing options...
