Painting metal?

[lincpimp]

Flat black spray bomb tends to attract dirt and be a bit difficult to clean...

I prefer semi gloss, that is what I spray on the various car trim pieces...

Best to wet sand with 600 grit paper, get some prepsol or alcohol and wipe it off afterward. A tack cloth (basically a sticky cloth that removes dust without leaving marks) is a good thing to do before you paint. Try to paint out of the wind, and out of direct sunlight.

Good idea to clean the whole thing off first with some powdered ajax or comet cleaner and a red scotchbrite pad. That will clean the grease off, so you do not sand it into the PC with the 600 grit.
