Spraying paint into plastic parts of case

post #1 of 9
Thread Starter 
Hi, I tried to paint my pc case and painting metals were fine but plastic stuff makes me headaches, I sanded, applied primer, and painted them 2 times and paint still seems to make such a weird stains and wrinkles, do you have idea why is this happening?

What paint did you use.

For plastic I think you have to use acrylic or plastic type paint so it flexes and sticks.

Im no expert on this so take it like a pintch of salt

i have used Krylon DUO paint on plastic bezels with good results. (Its paint and primer together)

did you use primer? did you sand the part? how was the weather when you painted? how many layers of paint is that? how far did you hold the spray can from the parts?

sorry for asking so many questions. honestly I have never experienced that kind of thing, so I need more info. but I'd advise that you use spare plastic parts or even plastic spoons to test before painting the actual parts.

yes I used primer, I did sand it (600grain size sandpaper) weather was a bit colder but really not freezing or so, this result was with 1 layer, but imemdiatelly as I started to spray, this happened. I spray from like 30cm far away and this happens only on my plastic parts, not metal parts

did the primer hold well? how long did you wait after spraying the primer? what paint did you use? if the primer worked, then the weather isn't the problem (at most it would make your paint job bad, but not like that), but I'm not really sure.

Check out a product called plastidip. It comes in tons of colors and is a plastic based aerosol spray. If you mess it up once it dries you just peel it off and reapply. Might not works as well unless you have a nice smooth surface.
