any kind of primer than can be sprayed over chrome stands?

Yes but first you must clean/etch the chrome with Muratic Acid. I suggest you do it outside, had a basement full of smoke the first time I did it. Clean the residue off and primer. I always use the self etching primer. I had gotten a bunch of Beaver J stands where the bases were toast but the J's in great shape. Painted the bases Gloss Black.

What does that mean etch? What do I do with the acid?

Etching means to treat the metal-aluminum,galvanized,zinc,chrome,etc-in such a way that the primer or top coat will stick to it.  It basically promotes adhesion. The acid does this. It does the same thing as sandpaper would do but without all the scratches, it roughs up the surface.

Most metal treatments I have used you just pour some on a clean rag and wipe the surface down really good.  I wear gloves and a respirator.

 

Self etching primer. It already has the acid and all that in it. It is a primer that you spray onto the clean surface and it will do the "etching" process.It is just another type of spray primer.

Or you can just follow Nick's advice.
