I've said it several times but I'll say it again.
My Paul Smart replacement tank was prepped and Caswell coated by my dealer that replaced my tank, it has several "pluses" and one "minus" on the tank right now. As much as I wanted the Caswell kit to work, it didn't. I certainly recommend trying it because it's all we have, but don't count on it to work.
