I've had my MOABs powder coated black for the past 2yrs and just now starting to look like they need some touching up.
I wheel it pretty dam good at the Badlands park so they've been seeing some more rock rash lately. I did do a touch up on them last year on them and you can't even tell the difference in them.
I only got charged $35ea for them at the time, 2yrs ago.
