TTi ceramic coating warranty

Has anyone ever taken up TTi on their 2 year ceramic coating warranty. Their website says to send your headers with a from to Engineered Applications, and they would decide if they would do the work or not. I'd hate to ship my headers across country just to be denied the warranty.

I bought my headers last april and put maybe 2k miles on them, by the fall the looked like the pictures below. My engine had about 5k miles on it when they were installed. What do you think?
