I don't know if they will hold up to heat or not. The bike I intend to use them on is far from ready for them. Hopefully any heat will just bake the paint on them.  Cliff.

Electrolysis or vinegar will get into places the wire wheel can’t. Have to watch vinegar, it’s slow but keep checking. I once shrunk a steel bolt with it, it wasn’t critical so no harm.
Actually I have a very thin wire wheel that reaches between all the fins.

I've always been able to get some chrome showing on the outer fins and just used the silver paint to cover the rusty area inside. Even "chrome" paint still appears silver to me.

It will be interesting to see how it handles heat.

Johnie,do you re-coat the bare spots after using that wheel ?

 These old clamps have been exposed to heat and the elements for 50 or so years. I haven't noticed my polished and painted ones fading away yet, but they live a sheltered life. If they look good for a few years, I'll take it.
No matter how many times you paint over a shadow, it's still there.

I have never recoated them after the wire wheel. My wheel is very thin. I don't over do it and they actually look very good.
