Gas Tank Sealer??

Custom Chrome recommends that their gas tanks be pressure tested
and sealed. The local shops in my area will test the tanks
but will not seal them because of problems they have experienced using
sealers. Is it really necessary to use a sealer? Will the tanks rust from
the inside out? I would hate to spend $$$$$$$$ on paint and have a
problem! Thanks

According to the latest edition of American Iron's "how it works" section...The tank needs to be sealed....but it needs to be done right. Pick up a copy and read their article covering the fuel system and you'll find their tips on how to do it right.

Almost any automotive radiator shop will pressure test and seal tanks. You can do it youself but it's not that expensive and the radiator shops do a good job.

Sealing tanks is a good idea. The main problem is keeping the outlets from the tank from plugging up with the sealer. you have to pour the stuff in and swirl it around and it seals EVERYTHING. You need to insert some kind of plug thru the inlet/outlets/breater bungs so they dont get clogged. I have heard of inserting coat hangers in there to unplug the holes before the sealer sets. My painter wouldn't even touch it because it is such a pain in the ass.

good luck.

I have sealed all my tanks but one and after a couple of years you can see the rust inside even if it is a little bit. Kreem is by far the best product for this application ! Just follow the directions to the tee and it works great. Tips: coat hangers work OK for the gas line outlets but I prefer to use a piece of braided cable. It's more flexable and I feel that it allows a good coating of the product to adhere to the outlet. You don't want to have a spot where gas can get behind the coating. That will defeat the purpose of lineing the tank. And excuse my spelling, I was a math major
