		 If it's an aluminum spool, regular high speed steel (HSS) bits would be fine.  Would be nice to use a drill press (lowest speed setting if set up for drilling wood) with the workpiece set up in a vise, but you could get away with a regular power drill.  Slow and steady. 
 
You could paint it with automotive paint and a pressurized sprayer.  Rattle can spray could work, but likely wouldn't hold up very long. 
 
A body shop may be willing to paint it for you?  Maybe you "know a guy"?
