first off, what do they do to get the original paint on, powdercoat??? my other tank held up good against gas, and all i did with that is completely removed all paint, primed, then rattlecanned it with some auto spray paint.. came out good, just not really smooth.. if OEM tanks were powdercoated im sure i can find a place around here to do it, i just need to know what paint to get. or should i just spraypaint, and hope it holds up for awhile against the gas.
