Fuel Tank Seal

I pulled my tank yesterday when I found rust floating in the tank. I am getting my car ready for paint, so it was no big deal. Anyways, does anyone have any experience about using the fuel tank sealer that seems to be floating around out there. If so, what did you use, and what was the best applicating method?
Thanks

P.S. By the way, it looks like this is the 2nd tank on my 73' roadster, and find it courious that there was rust in it anyways. The tank is in very good condition with very little surface rust, and no leak what so ever.
 
To the radiator shop with it. A dunk and then the liner stuff. Eastwood has some effective epoxy for the purpose, IIRC.
 
Yep, to the radiator shop...have 'em boil it, pressurize it to check for leaks, & then have them chemically line it...expect it to be in their shop for about a week....overnight at least in boil tank, 3 or 4 days for the chemical lining to dry sufficently.
 
Mine done as Tony suggests works just fine and is 48 years old this month.
 
I had them do mine. Boiled, etched & sealed. It was pricy but less than a new tank that would probably crap out sooner than later. I debated doing it myself but dealing with chemicals/Kids and their disposal - chemicals not kids /bcforum/images/%%GRAEMLIN_URL%%/smile.gif made me think about just sourcing it out. I did blast it, primed it with an etching primer, then I coated it with semiflat black acrylic polyurethane. I think she's good for a bit wouldn't you say? Here the before & afters:

During the past year there have been several threads about tank linings including DIY options. Rather than repeat them all here you may want to return to the root forum (forum list tab above) and search using keywords such as Kreem (in various spellings) and set the way back machine for several months.

If you don't have a lot of varnish in the tank you can do a good job yourself.

I like the POR-15 kit. I simply use some phosporic acid to etch the tank and remove any loose rust. then a little "Marine Clean" to act as a degreaser. Then I wash it with a good detergent...several times and give it a good rinse.

let it dry a day or two and coat it.

I've done several tanks and never had a problem. If you have a lot of varnish it's advisible to use a pressure washer to loosen most of the crude. Laquer thinner will help soften the varnish.
 
Thanks, I will either try the POR 15, or something my dad recommended in JC Whitney. The tank is in pretty good shape in and out, no varnish that I can see. Anyways, thanks for the input, I think I will do the ole do it yourself method with this one.

The stuff I bought from JC Whitney was Kreem. However, they may have started selling something different. Having used POR and Kreme, my advice is use POR. See the other threads for why.
