Do it! Also, have it pressure tested. We had a tank come in and get painted that was coated and had a small pin hole leak in one of the welded seams. Had to repaint the tank a few weeks later. Not our fault, this was brought to us by a local shop "ready to paint"guys is it necessary to to seal the tanks or just recommened?
How did the application of the Caswell kit turn out for you? Did you use their Epoxy Tank Sealer kit? I've given up on locating a company locally that will nickel plate my tank and am considering the Caswell epoxy kit.well shops in area are limited...i ordered a sealant kit sold by caswell plating...see how it works....i know the prep is what will make or break the project....yaffe told me they nickel plate all there builds at the shop he also said some use some stuff from harley...called it a primer.... or they said kreem...and ive heard alot of negatives about kreem
