View Full Version : A Few Painting Questions

I'm picking out my case right now, but I just want to know which would be best, colorwise for painting it black.
I'm pretty sure I'd have a hard time getting the primer to stick on plain metal. So should I go with a case that is already black? Or does it even matter as long as it isn't bare metal??
The Antec cases that are metallic, those are actually painted right? And not bare metal..

I have an antec. I sanded it down to the bare metal. I painted it, with no primer, and it sticks. I should have used a primer for a better looking finish, but it works. And, I think the case are not really painted, but like powder coated, but not really powder coated(like a cross between). You should be fine though.
if bare metal is properly cleaned paint and or primer will stick to it.

yeah, you want a metal case.....aluminum doesn't always take paint so well.
don't bother sanding that metal case down to the metal, just sand enough so that all the paint is sanded down, then prime it.
let the primer dry, then sand the primer with something like 1000 grit sandpaper..
then spray your paint over that.

I have an antec as well, sanded it for the most part, but still a little paint left on, sprayed three coats of primer and four or five coats of black, sanding after each with 1500 grit sandpaper (yeah I know it's high for that stage of painting but it was that or 300)

It isn't necessisary to sand to bare metal when you are painting a case (or anything) but it won't hurt, either. Remember, at some point it was bare metal and the paint you have now stuck to it somehow. ;)
The rules for painting are the same regardless if you are at bare metal or if you leave some of the older coats on. Sand with medium grit paper to knock down the old paint and get a smooth surface. Then, before you shoot your first coat of primer, go over the surface with coarse grit sandpaper.
You do this to improve the grip of the primer on the surface. Now, why do you need to use primer? Primer can effect the tint of your final color, a red primer will create a slightly brighter color than if you use gray primer. But the big reason is because primer is like the bread in a sandwich: Its not what you went to the fridge for, but it does a great job of holding everything together. Good primer etches the metal and bonds the primer to the surface, while being porous enough to allow the top coat of paint to bond to it.
Primer is essential if you are working with bare metal. If you've only knocked a few layers of paint off your case it can be optional. But be warned that lighter shades of paint, like that phat tangerine orange you've been eyeing at the Voodoo site, magnify any faults in the top coats like orange peel and runs. And primer is one of your better defenses against that.
One last tip: If you are serious about getting a good homemade paint job, skip the Rust Oleum display at WalMart and find a good local paint jobber. These are the guys who sell paint to the body and paint shops in your area, and most will mix up rattle cans of high quality paint in any color you want. It will cost more, up fifteen dollars a can, but its a difference you will be able to see.
Oh, about aluminum: The difference is in the primer. Aluminum demands a special primer, it has to do with the microscopic etching I mentioned earlier. But aluminum primer is widely available, and once you get the primer on you use laquer or enamel like any other paint job.
