Same thing happened to my TTIs. Started surface rusting within months of install, in Dallas Texas no less! We are not known for rust issues around here. I called to inquire on the warranty, and they informed me that I would have to call their coater directly, which went no where in a hurry. Doesn't make sense to me either?? You pay the $$ for quality, and then you receive the run around when there are quality issues.

Regardless, their fit is great. I just wish the coating and customer service were better.
