painting aluminum?

post #1 of 15
Thread Starter 
So, I'm working on an aluminum case and while looking at other mod's, the question of how I would paint my outer case came to mind. It'll be in the form or brushed aluminum that I need to know about painting. What if any paint will do a good job of sticking to aluminum, and what do I need to do to get it in shape to paint? Primer still? Will primer and paint "fill the grooves" in the brushed alu? Will paint even suffice? Do I need to go to annodizing to get a good strong long lasting virtually scratch proof finish? (not that that's possible, just don't want a minor scratch to bring out silver b/g) Will Batman survie the evil doings of the Joker and Mr. Freeze?...


Thanks any and all who have an real answer.

Anodizing would provide the most durable finish... but it is still possible to paint aluminum. For instance...people paint aluminum airplanes every day.

However, it is a more involved process than painting steel. Painting brushed aluminum will probably be even more of a challenge.

Here are some links to give you an idea of proper surface prep when working with aluminum:

Thanks, I know about painting things like airplanes of course, though I didn't think about it until you reminded me. I guess I shoulda explained it better.

I want like the "colored" or similair to annodized look with paint. Using metallic car paint I suppose would be a good choise to start with?

Car paint is best. CD recommended me Duplicolor for my case mod (aluminum, Stacker 810). I primed it with 2 coats then put on the Duplicolor high gloss black. Its really durable and I'm on my 3rd and final full coat.

The only paint I can think of that will give that "anodized look" is Metalcast by Duplicolor--a real PITA to get right...

And because it's aluminum to make it really stay on there for real you need to use a self etching primer (Duplicolor of course) which is a fugly green color--then laydown a nice ground coat of metallic (Part of the MetalCast system)and then finally the translucent color coat.

It'll work/last/look great...just got to go through hell first.

CD, if the look is worth it in the end, or what the look should look like, then it may be worth the heck I go through.

You should look into "home anodizing" if you are really serious about working with aluminum.

Google is your friend

I have seen many DIY anodizing projects with downright impressive results.

Examples:

I personally painted parts of my brushed aluminum Lian Li case for a mirror finish, lemme give you the head up.

Yes, it is entirely possible and easy. You really just got to rough up the metal before painting. Sand it down with..say..a 120 grit sandpaper. Then make sure you give it a good few coats of primer.

Use RUSTOLEUM.

Anodizing is a little different. You can tell. I can't really explain, but it is like a transparent shinyness. Not like paint..which is thick.

LOL..that sounded dumb
