Where to get TTI Headers Recoated?

The lifetime warranty from jet hot sounds like a good deal. Only caveat to that is shipping that's gotten so expensive. I just received my lifetime replacement on headers and one way shipment was 70 bucks. I'm betting you must pay both ways shipping to them.
I just purchased Zybar to coat the outside of my headers. For the inside I bought eastwoods internal exhaust paint with the 2ft long applicator tube. Hopefully it will last awhile-never tried either product.
