Fow what it's worth, they took good care of me. Hopefully they are still around. They coated a pair of headers for me in about 1997. In about 2014, they were looking a little rough, so I called them up and asked them about their warranty. They said they wanted a number they engraved on the inside of one of the flanges. The number was there, they said it was their number and I mailed them in. They re-did them for free and even paid return postage. Good luck
