73crownwagon Posted August 21, 2014 Share Posted August 21, 2014 my front valance on my chevy vega is unfortunately made from PE, and was snapped in two parts so i got it welded back together. its super faded plastic from being so old so needs a paint to look nice on the car but fuck me its not easy finding paint that will adhere to PE. ive called around the car painters and theyve all come back saying "use plastic adhesion promotor it works on all bumpers blah blah blah" i dont actually think they know what PE is cos i sprayed some plastic adhesion promotor on and it runs off the PE like water on a ducks back! google says a spray paint called Kryon Fusion works on PE but i cant find a single place that stocks it any ideas???

danger Posted August 21, 2014 Share Posted August 21, 2014 Did you give it a wee rough up with sandpaper so it feels kinda furry? I'd do that then just lay on some epoxy and see if it works. Quote Link to comment Share on other sites More sharing options...
73crownwagon Posted August 21, 2014 Author Share Posted August 21, 2014 yeh buffed with 80 grit then 120 grit and the plastic promotor ran off like a hussy Quote Link to comment Share on other sites More sharing options...
danger Posted August 21, 2014 Share Posted August 21, 2014 I'd give it really nasty with 80gt then try a thick coat of epoxy primer if its not a part that flexes much Quote Link to comment Share on other sites More sharing options...
73crownwagon Posted August 21, 2014 Author Share Posted August 21, 2014 it probly will be flexing in the wind being its the front of the car plus i have to bend it a little to get it to fit on. Quote Link to comment Share on other sites More sharing options...
danger Posted August 21, 2014 Share Posted August 21, 2014 I'll ask our one legged chemistry wizard if he has any ideas Quote Link to comment Share on other sites More sharing options...
JoKer Posted August 21, 2014 Share Posted August 21, 2014 sounds like you need some etch or something, 120 sounds too smooth tho (spitballing here never painted plastic before) Quote Link to comment Share on other sites More sharing options...
73crownwagon Posted August 22, 2014 Author Share Posted August 22, 2014 the fact that google doesnt say it works with PE im going to say its not going to work. a canoe website says maybe a acrylic latex paint will do. can you get this in a can?

ajg193 Posted August 22, 2014 Share Posted August 22, 2014 It is a plastic coating that you spray on like paint, supposed to be quite good. Quote Link to comment Share on other sites More sharing options...
Mof Posted August 22, 2014 Share Posted August 22, 2014 Heat gun works good for bringing the black back in to pp. I can't remember if it works on pe Quote Link to comment Share on other sites More sharing options...
73crownwagon Posted August 22, 2014 Author Share Posted August 22, 2014 I have heard that aswell. Problem is that it's red PE and he's welded it back together with black PE filler lol. I have no choice but to paint it now. I have considered 3M wrapping it Quote Link to comment Share on other sites More sharing options...
Beaver Posted August 22, 2014 Share Posted August 22, 2014 Id be tempted to try plastidip as the others have said. http://www.trademe.co.nz/motors/car-parts-accessories/performance/other/auction-769973858.htm Also for the price of a can of normal paint (ie fuck all) Id even give that a shot.

The Bronze Posted August 22, 2014 Share Posted August 22, 2014 I picked up a litre of K&H PlastiPrime at repco on sale coz one day when i get round to it (ie. if I get round to it) I want to paint the spare bumper i have for my shitty ute. It says it works on polythene according to the back of it, you wanna give it a whiz? Or you not doing whole thing, just a patch? Quote Link to comment Share on other sites More sharing options...
