    Does anyone see anything wrong with undercoating a tank? I was gonna undercoat mine so it doesn't squeek, but was thinking that Could in doing so would it trap moisture between the coating and the tank and be promoting early rust?

    It would be the same as undercoating the rest of the vehicle I would think. If it doesn't affect the rest of the metal it shouldn't affect your tank.

    I'd just make sure it was clean and dry before doing it.

    I undercoated mine about a year ago just after I bought it as well as the rest of the under side and haven't had any kind of problems with it since I did this.

    Thanks, (in advance)

    Well it'll make it look spiffy but not offer a whole lot of help. The problem with tanks is that they get condensation on the inside which causes them to get rusty and leak. I just painted mine up primer gray and threw it back in there with new straps and under coated my skid plate. When the tanks all black it makes it harder to spot leaks when opossed to a lighter colored tank. They make kits to stop that squeak, I think LMC has them. If you do undercoat it be sure to use the kind you put on with a rocker shutz gun and compressed air, it goes on heavier and has a tougher consistentcy. I think Transtar makes the kind I used. I don't know if the average Joe of the street can get it or not because its only supposed sold to body shops and such.

    I've been successfully using 15# roofing felt, and have no squeaks whatsoever. I put sections over the top part of the tank at the front and back and strips under each tank strap.

    Works great.
