FUEL CELL

if im going to build a steel fuel cell. i need to coat the inside with por-15 after prepping the metal with marine-clean and metal-ready???? is that correct??? or is there anything else i could use to coat the inside of a steel fuel cell??? any help is appreciated.

Industrial Powder coat maybe???

Don't use actual Por 15. Get there tank sealer kit. You can do pretty large tanks, and its meant for coating new and used gas tanks. It comes with everything you need. Cleaners and the coating, and its fairly cheap. $20 was enough for me to to 3 large motorcycle gas tanks.
