Does someone have a tried and true preference for a sealer for a 1924 Touring gas tank? I'm having the tank boiled, and would like to seal it. It has some rust, but I don't think it is bad and there are no leaks that I know of. Thanks.
Caswell Plating can provide you with Phenol Novolac, an outstanding epoxy tank coating that will seal and rustproof any metal or fibreglass tank. I have repaired about 10-12 tanks with their product with zero problems/failures to date.
I found out about their product from a high end custom car builder, classic car restorer in our town, who told me that this product is what the "big boys use"... for what that's worth.
Ditto what John said. I have done 3 motorcycle tanks with the Caswell product and none leaked a drop. 2 had multiple pinholes.
Por15 and kwk poly are both good both are ok with new type fuels
Both Johns,where do you get this stuff?
Well, here's my unsolicited two cents worth!...Coating an old tank is OK for sure, but with all the baffles, sharp corners far from "the hole", etc. how can one be sure that the tank will be truly coated everywhere? Only takes a small area with uncoated rust to screw things up sooner or later. At the relatively affordable price of a new tank, why not treat your car to one? Fortunately 3 of my T's have such new tanks, and I'm glad for it! JMHO
Don't do it. Find a good used one, or buy a new one. They are around. Don't trust that stuff!
I'm more shadetree than that. I say get the majority of the big stuff out, then use one of the in-tank screens. Anything small enough to get through the screen will go through the carb with no problems. Even if the gunk were to build up around the screen, it will act as a stand pipe and the fuel will flow through the exposed screen above.
'Course, if you have a 26-27, then you have to do something different.
We have been using the coating that we get at the auto parts store in Model A tanks. You can't just go out and buy a new one. We take the tank to the parts stripper that does bodies and they are acid stripped (they do our blocks also). Have been using 2 cans of the material. Dump it in and roll the tank every so often over a couple of days. That includes end for end. Drain it out, save the extra and let the tank cure for a few days open. So far so good.
