My gas tank is okay on the outside, but the inside is full of scale, rust, crud, and corruption (normal I suppose). I have gotten most of the loose stuff out by rinsing with water and shaking. Are the tank sealants most of the distributors carry the way to go or are there other suggestions or opinions?

If it isn't a 26-27 gas tank, I would buy a new tank. You won't regret it. I do sell them, email me at aloso@q.com if interested.
Replace the tank with a reproduction. I learned the hard way by chasing gas tank gremlins for years, only to solve the problem with a nice new galvanized repo tank.
I second that. I could never go more than a few miles without a fuel clog until I sprang for a new gas tank. I even tried having the old tank cooked out at a radiator shop, but it didn't work. 80 years of crud is hard to clean.
I just finished the POR-15 treatment sold by Lang's and others. First the Marine Clean with several treatments and then the Medal Prep treatment with good rinsing. After leaving the tank in the hot sun for two days, it was completely dry. Then use the POR-15 tank sealer and roll it around good. It is now going through the drying period but looks clean and smooth with the coating inside. No loose particles shaking around either. Didn't cost much and got to use my original tank. Hope someone else might comment on this method.

I've used this product on 4 gas tanks so far (3 motorcycle and 1 T).

Results have been excellent in all cases. One of the motorcycle tanks had some rather large pinholes. Sealed that one 4 years ago and still fine.

I had a nightmarish experiece with the fuel tank sealer from Eastwood. The car was a '67 Mustang convertible. We sealed a brand new gas tank (car owner insisted against my recommendation). I believe the Eastwood kit is actually a relabeled Bill Hirsch product.
About a year later the car started to have problems with clogged fuel filters, then would not flow any gas at all. The carb, fuel line and filter were all clogged severely with the tank sealer which had softened and come loose completely. We replaced the fuel tank, pump, and lines. The carburetor had to be sent to Pony Carbs to remove the goo.
Best bet is to buy a new tank and avoid this crap.
Another problem with gas tank sealers is what may work with today's gasoline may break down with the next new additive.
Bud has it right... Phenol Novolack is the best. Your tank will be better than new, with this stuff.
