TTI Header Coating

I got the ceramic coated TTi's 2yrs ago and they are already showing surface rust- mostly around welds and by collectors. Read the warranty info... covered but you have to obviously remove/return and then its at their discretion for re-coat and return postage. They fit great but expected better quality. I feel they know that the hassle of removing and shipping discourages most of us. And we say- whatever... Pay big money for "the best"... not real happy.
Has anyone ever sent them back?
