Seems out of stock every where.
I have a tank I got off craig's list for pretty cheap. After giving it the evaporust treatment I found some pin holes. I was able to patch them from the outside with JB weld. It holds gas and doesn't leak but I'd feel more comfortable sealing the inside for prolonged contact with fuel. Anyone use the KBS system?
they claim it ill be available again in mid October

hmm....Not sure I have the patience to wait til October.
I've used the KBS system on two different tanks now. Works very well.
