Mine have pretty good scratches/scars on all of the them from rocks. No paint could have held up any better. No blistering or corrosion though. Good thing is the aluminum is gray so the scratches don't show as much as if they would have been black painted rims. Also, I've sheared off two valve stems, a buddy has done the same, not sure but I think other rims might have the valve stems deeper into the rim to avoid this.
It is kind of an evolved lift. Started out as a Teraflex 3" with Rancho 9000x adjustable shocks, ended up with 4" pro-comp springs, RE lower fixed arms, RE adjustable rear uppers, and finally Rokman front uppers. Funny the only thing TeraFlex left on it is the sticker and the rear sway bar links.
I got quite a bit of rock rash on mine all the way into the "spoke" area that lead to the clear coat coming off pretty substantially. Not the wheels fault, probably would have happened to any. Now I'm running black powder coated aluminum and I've already beat them up too. I need a mall queen. Haha.
