True. Need to see if I can find my paperwork. I'll shoot Robbie a message just to see. I mean, I didn't seal the wheels until now, but I washed them regularly and never let them get to a level of filthy that would warrant any kind of issues. And when it was snowing/salty I rinsed/washed them every couple days. So I feel like they shouldn't be pitted already. It's only on the fronts so it seems to be from the brake dust, but I've got low dust ceramics and I've run the same brand ceramics on other chrome wheels that were never sealed and never had an issue.
