Painting polished stainless steel
I've been painting a bunch of parts using urethane stuff including an etching primer. I doubt that an etching primer would etch stainless or anything chrome plated. Any suggestions? Thanks!

Bead blast first.

Re: Painting polished stainless steel
Even with self etch primer the paint will eventually peel. As deuce mentions bead blasting is probably the easiest to get complete coverage for the primer to bond to.

Re: Painting polished stainless steel
I would not bead blast as it is not aggressive enough, grit blast instead.
You want to remove the shine.

Re: Painting polished stainless steel
320 grit paper will work just fine.

One of the course industrial grades of ScotchBrite will work as well.

Re: Painting polished stainless steel
Thanks. I just started attacking an old rusty crusty Model A grill shell that I also want to paint. I'm using a Harbor Freight Poly Carbide wheel. It's working pretty well on what's left of the chrome. I'll use it on the stainless as well since it leaves a pretty nice but abraded surface. I also have some garnet abrasive media that I'll give a whirl.
