I kind of figured these weren't high quality. If they last me a year I'll be happy, and will shop around for something else, maybe the all metal ones that someone else posted
I wonder if some kind of coatings could help the situation, wax or a high-heat clear coat?
Maybe coat the entire thing with this stuff? Reading through the asked questions, one guy successfully used it on a turbo.
