REFLECTOR: Painting aluminum

[Andy Millin]

Suggestions please,

I have some aluminum pieces that I would like to protect.  I'm a novice when
it comes to paint.  I have tried to paint some aluminum parts before and it
was dismal.

Small parts.  I cleaned them with a DuPont prep-wipe first.  I used a spray
can acrylic.  It looked good, but did not bond; flaked off by just rubbing
it.

I would like a clear coat.  It is just pieces.  Probably no more than 4
square inches.

Can anyone recommend something?

Thanks,

Andy
