Which paint for frame and suspension

[redcali]

I just discovered the magic of wire-brush-on-a-drill. (not to be confused with hot-dog-on-a-stick). I cleaned a test section of my frame and wow! Didn't want to leave bare metal so I sprayed it with the only black paint on hand.

Well. next trip to home depot, I got a sand-blaster and a sack of silica.

Question A: Is there a reason I shouldn't blast the frame where the brush might not reach? I want to avoid big dust where possible. I'll be doing this out front and plan to hose everything off afterwards.

Question B: What is the best choice for paint to use on the frame and suspension? I am considering undercoat for the body later. Maybe not, as I live in So Cal and not much of a rust problem. Definitely want to look nice underneath. I assume I won't need primer first.


GOD BLESS AMERICA.....

I used por15 black chassis paint, worked great, looks excellent, the only thing about it is that its uv sensitive which means it will turn matte and grey if exposed to light or welding. They have a topcoat that you can put on over it to protect. The stuff is great if you prep everything like they suggest, if not it peals off like paper.

I really like Eastwood rust encapsulator. Main reason is that it is a one part system that needs no extra steps. It levels very well and won't leave brush marks if you do it right. You can also thin it and spray it.

thanks for the info. Unfortunately, my time and money are split between projects. I am limited pretty much to spray paint, probably from a Home Depot or Auto Parts Store. Sucks, I know. Sooooo, what's the best given my situation? Thanks everyone...

In that case, I'd say go with Rustoleum, and it might even make more sense to brush it on for better coverage. Apply a rust inhibitor first if you can swing it. Just my $.02...

What ever you decide to do, use a respirator if you are blasting with silica! I plan to use rustbullet, btw.

I like spraying zinc(cold galvanizing spray) on things such as the frame & places where disimilar metals come in contact-- works good for the frame since it protects surrounding metals even when not covering every spot such as spraying it inside the frame-- looks probably will not win any shows ,but it is effective against rust

I used the por15-silver. this stuff is tuff! but everywhere the light hits it, it has tarnished. this stuff does not like the uv's-use a top coat on it. the picture is kinda bad, but ya get the idea...it looks alot better in the pictures when wheeling. it just looks more detailed.Chuck

I used Rustoleum Hammer right on mine. If I had to do it again I would go back and use their Rustoleum Professional Line. It's a hardened enamel and seems a little more durable than the Hammer Right. MAKE SURE you degrease extremely well when using a spray paint. I stripped and did mine the first go around and didn't get the frame clean enough and the stuff would chip if I looked at it the wrong way. I ended up having to go back and do it all again %). Worked much better the second time around.

wear a respirator with silica

I wouldn't hose it off, water + raw steel = quick rust

This is gonna make me sound really red neck, but I am planning to use Rustoleum paint in the little quart containers and just brush it on. I have used POR 15 before with mixed results, and this way even if it does flake of peel or chip, I can whip out the paint and do touch up.
