I know my gas tank will be getting a coating w/ SPI epoxy as soon as all the small parts are ready on my 1949 Chevy 3800. I bought a new replacement tank 3 years ago and when I pulled it yesterday in preparation to pull the cab off the frame and start the bodywork, it was already starting to rust. Guess the old zinc ain't what it used to be. There will be 6 things on this truck that won't get SPI Epoxy - stainless, chrome, glass, plastic, rubber, or vinyl. Everything else will!
