Galvanized???

post #1 of 7
Thread Starter 
Hello all! I'm looking to paint the inside of a computer case I have, but I think it has galvanized coating on it. My plan is to take it to where I work and sand blast it before I paint it.
But I'd like to just make sure it is, before I go through the trouble. The case is a dull grey color inside. I've attached 2 pics. What do you think?

I dont believe that it is galvanized. Usually anything computer related the is galvanized has a slight shine to it from the zinc. It should be either a paint or powder coating. Im leaning more towards paint.

This is what I mean as to what a galvanized case should look like.

Dont paint just yet. If you can sandblast the case it will make things so much easier for yourself. If you cant sand blast it try to rough up the existing "coating" with some sandpaper then wipe it down with some mineral spirits. Then just top all that off with a few coats of self etching primer and you will be good to go. That way you will have a good base for a good looking paint job. thumb.gif

One more thing. I have always sand blasted my cases before I have painted them. The biggest thing after that is getting an air hose and really doing a thorough job of blowing out all the nooks and crannies. Then go over everything with something like paint thinner or mineral spirits on a rag. There is usually a little layer of dirt left behind that you will want to get off before you paint. Then after that use a tack cloth to do a quick once over. I learned the hard way when I painted my Antec 900. I just shook the sand out of the case, wiped off what i could see with a terry cloth thinking that would be good enough, then went and painted. Unfortunately some of the paint had begun to peel after 3 days of drying and it looked terrible. I had to strip it and re sand blast it to get the paint to look decent.

Also a great thing to use after sandblasting anything because it removes oils and is self drying is a liberal helping of brake parts cleaner. You can find it at any auto parts store or walmart for about 3 dollars a can and it does wonders. Just be careful don't get it in eyes breathe it in or have it by fire as all of these things will be bad and it comes out with force wear safety glasses.

Just my two cents, it has always been a policy of mine to spray any sand blasted item down with this before going on to powder coating or painting.

Thanks, Joe
