So, I've come across multiple guides on case painting and noticed that they were all more or less for metal surfaces. I just have a few questions before I start painting next week.

The only primers I've been able to find at my hardware store is for metal surfaces, this leaves me to ask if plastic surfaces need primers. Another question is that I've read that prior to applying primer, the surface should be rough and not smooth in order for the primer to hold better, is this true? And thirdly, can metal surface primers be used for plastic?

Finally, I've been test painting a few buttons which are also plastic, and at the edges and corners, the paint just doesn't stick on there. So it looks as if the button is worn, except its just been painted.

Thanks
 
Oh man is that stuff great for jeep fenders. Made mine good as new. Ive also used it on some other plastics, and its worked wonderfully on them all.
 
I also used krylon fusion on some car parts, interior panels. It works really good if you prep them correctly, which for this paint is basically just cleaning and de-greasing. I just wash them and then use an alcohol or paint thinner to remove any grease.

I did a couple coats, but it still scratched, so I went with 1 coat of clear on top and its bulletproof. Clear is not needed unless it will see a lot of abuse.
 
so another quick question, what kind of polishing compounds are recommended for spray painted surfaces? I actually googled this and got less answers than I expected. I went to AutoZone.com and surprisingly found only one product. Is it even appropriate to buff spray painted surfaces?

There is this cool buffing attachment for the dremel, and I want to try it out. :D
 
Maybe look on the Autopia.org forums? Those guys are super hardcore car detailers and they might be able to help with the polishes.

Personally, I think you could get away with not sanding at all, or just sanding at the very end with 2500 grit, then a rubbing compound, then a polish.
 
You might want to try your local auto parts supplier. I used to go there all the time when I dyed/painted some of my interior pieces in my bmw and scion. If you use the right stuff, it should come out looking as good as stock and won't scratch off easily.
 
krylon fusion is amazing, i used it on my truck once for the tail lights. been using it for pc cases and everything else since.
