Um....I think there was a thread a few months back about powder coating
wheels.
If I remember correctly, numerous people chimed in with (in best
knuckledragger voice) 'Powder coating too expensive! Rattle-can
easier/cheaper!'
Issues abounded around the coating chipping/not holding/cracking/etc,
etc....
Anyway, to each his own. But I do know that Eastwood sells a powder
coating kit for around 200 samolies with a collection of different colors.
Eric! Whaddaya think of your Neon with an orange, yellow, green, and red
wheels each? :-)
Enjoy!

Umm, Eric? Aluminum alloy is an excellent conductor of electricity. :)

The temperature and duration at temperature for baking the powder coating
is considerably below that where I'd even start worrying about
metallurgical changes to the base metal. Keep in mind that powdercoating
is becoming increasingly common at the OEM level because it's tough/chip
resistant, economical, and ecologically sound (no solvents, any powder
overspray is collected, filtered, and reused). OEMs are powdercoating
major structural parts (like frames) and yes, road wheels.

I don't know if I'd hit alloy wheels with anything stronger than, say,
baking soda from a blast gun. Beading, even walnut shells could really do
a number on the metal's surface finish, requiring polishing before
re-coating.
