[R-390] Painting Knobs

[Les Locklear]

Like a lot of things, it has probably been banned. Many years ago, when I was a service manager for an automotive dealership we used it to combat corrosion problems on battery terminal posts. Clean them, spray with zinc chromate primer…end of problem. Most of the R-390’s I’ve seen have yellow ( zinc chromate primer) as a base for painted parts. The batteries these days don’t seem to have the same problems. Hey, I’m old this was over 50 years ago in the early 70’s. I still have a rattle can of it. Does it work? I don’t have a clue or an R-390 series receiver anymore. I just read for memories from old friends.

Yep, it was the name of the yellow stuff that can be found years ago.
