Cleaning engine parts like alternators.

What's the best way to clean them and prep them for paint? Just hit them with some 220-400 sand paper, blow them off with compressed air then brush on paint?

Use brake cleaner to prep them after sanding, as well...

It is notorious for cleaning very well, drying fast, and leaving no residue..

Thanks for the info.

good carb cleaner I find generally works better. 2+2 = teh win for paint prep. Just be careful what and where you spray stuff. It will dissolve the varnish on the internal windings, possibly causing shorts. If you really want to paint it, I would probably take it apart and paint the case without the guts in it.

I'll scuff it up and blow it off. Wipe it clean with brake or carb cleaner and paint with a brushable, high-temp silver paint.

Don't use carb cleaner, it leaves a mild lubricant on the surface.

Use brake cleaner.

I just bolted it on. I'll remove it and take it apart when I paint it.

Some carb cleaners do, not all. Most of the higher priced ones do not leave an oil residue. Good carb, or brake cleaner does work very good though! I would also recomend removing it and painting just the body.

:stupid:
2+2 doesn't leave a film. Cheapie Advance Auto crap does. The Wal-Fart junk does too.
