Fuel tank sealer
 

At some point I think I'm going to want to seal the fuel tank on the '77. I haven't been driving it often enough :oops: and I'm sure that the gas tank has gotten rust in it (or will at some point) due to condensation (I try to keep it full and use preservative). So the question is... Does anyone have any experience with any of the products out there? POR seems to have a product that would do the trick.

Thanks.

I used it on my MG with good results.
