What color you want?
If you stick to the phantom black, they sell it at quite a few retailers.
If you change to silver like I did, then you should go to an epoxy urethane enamel or imron for durability, I tried the good ol rustoleum, some flaked off in 1 day doing 10-15 mph so it wont last worth a damn
If you have expendable cash, might try powdercoating it, heard good things about durability.
I plan on just polishing the lower half of my drives when I get her back, hell it is aluminum, it will polish up nicely with enough time spent sanding and buffing and using different sand paper grits and polishing compound on a buffer wheel.
THen im going to clear it with a urethane
Leaving the top black
Talk to you soon Bro
PS more prep work you do, the better the end result and more durability you will have
