Built a 150 Liter diesel tank. Used epoxy and then painted the inside with red then white CARBOLINE 2 part (epoxy) paint. The red helps telegraph any holidays when you put on the white. Works like a champ! You'll have to look for the source for the Carboline - but as I understood its an "industry standard" for fuel tanks. Maybe Wicks Aircraft supply or Aircraft Spruce? (the company).
Be sure and pressure test at about 5 - 10 psi-- if no leaks -- you're done!

Experience is the BEST Teacher. Is that why it usually arrives in a shower of sparks, flash of light, loud bang, a cloud of smoke, AND -- a BILL to pay? You usually get it -- just after you need it.
