I had a contract with Budweiser to paint all their trailers and trucks for about 10 year's in the 90's.
We had to paint outside as we did not have a shop big enough to get the trailer's in.
We would sand the old paint [using 320 grit paper] down enough to get good adheision with the paint, no need to go to bare metal.
We would then use a good PPG primer [gray].
The paint we used was a single stage paint which shines real nice when set up and cured.
Looked good rnough for Bud.

I think single stage urethane would be your best bet, it's tougher than basecoat/clearcoat.
I painted my boat with it and am amazed how strong it's been against all the stuff I hit with it.
Putting it on over epoxy primer makes it tougher.

Thanks guys, since it is aluminum, is there a special primer? If I use epoxy primer, do I have to use a regular primer over it. Also, do you have to let primer dry and then sand and coat it, or just let it flash and the go right to paint? Also, if I use a metallic silver, can you buff it? Would a pearl flake be better than metallic with ss paint? Wish I could afford to let someone else do the paint, but the one quote I got was way out of my range; I do have a compressor and a devilbiss plus gun, so if I can do it, I might as well give it a go, can't look worse than it does now.

Thoughts on the gun doing what I am talking about?

Thanks again

The harbor freight ( sorta) hvlp guns do a decent job of material transfer & atomization ( about $20 ) , single stage paint with a catalyst . Even rust oleum has catalyst ( gloss retention less UV damage) I'd see if there's a semi gloss/ satin finish available , boo on metallics , solid color is better ( touch up or matching is far easier )

Some urethane metallic colors can't be buffed without disturbing the metallics
and making the paint look different in places.
If I am planning on cutting and buffing a urethane metallic I'll
spray some clear coats over it to make it more buffable.
Works quite well.

 

[MrScott]

Okay, so I will stick with a solid color, now what brands of ss urethane do you guys recommend, and what primer?

I called UreKem and after discussing where I live and my project, they think I should use bc cc. Now I am questioning myself.

 

[gregaba]
