fuel tank coating

[bean]

i have a 69 that has set for quite for a while and i know the gas in it has gone bad. can someone recommend a coating for the inside of the tank? i'm not real crazy about the quality of the aftermarket tanks. any other suggestions? thanks.

why coat it? is it leaking? just take the tank to a radiator shop and have them boil it ou and go from there

you don't want to "boil out" a tank. With any luck, a rad shop would never do that anyways.
A rad shop could clean it out for you, and they would probably try and talk you into a product by POR or another called red coat. I would not bother with any coat without having the tank cleaned.
I would recomend the red coat personally... I have used both.

*edit*... it may be red kote

I'm opposite of Andy. I too have used both, and much prefer POR15 to Red-Kote. I do a bunch of antique motorcycle tanks with the stuff.

If you decide to line it, I would go with the POR. I have used many of their products and have never been disappointed.

I would just clean it out myself and put on a good gas filter.

My brother and I just went through a similar situation with our tank. I would suggest cleaning it out VERY WELL. We had issues with ours to the point where the pickup tube from the sending unit was getting clogged and shutting down the motor consistently (even with all new gas lines). Don't just spray in the tank and dump it out. You'll miss the "crud" that is stuck in the corners and around the bottom of the tank. We took out our sending unit and removed the tank and used 1 gallon of carb/parts cleaner from Auto Zone. We let it sit on each side for 30 mins each ensuring all sides were coated with the cleaner well. Turned it up on the side and sprayed water through the filler neck. Fill it approx 20% full and have someone get the opposite end, turn it horizontal and shake back and forth (kinda like an old fashioned saw). Dump it. Fill it with the filler neck toward the ground and the other end standing vertically and spray again through the sending unit opening. Shake it again. We repeated this process for over 30 mins and removed about three cups of sludge/mess/uugghh stuff. Payed off bigtime. We didn't coat anything and haven't had any issues at all. The only thing I've heard about the coating process is that the bond isn't going to be very good unless it has a good surface to bond to. I.E. the inside has to be clean and free of debris. If you don't get everything else out, you may wind up having dislodge under driving conditions and then you'll have a bigger fuel system issue if it makes it the carb. Just my two cents. Good luck with the tank!
