what all can u build a fuell cell out of, i know i cant weld stainless, and aluminum, could i use 1/8 or 1/16 steel, and coat it in something? i would love to build my own tank
Heres some stuff to seal fuel tanks. Its an epoxy that you put in the tank and then roll the tank around to coat the inside.
