Re: Gas Tank Liners
when you coat the inside of a metal tank you need to clean it well with a soap solution, rinse it out, then etch it with a phosphate solution, then make sure it's compleatly dry inside before you coat it. if you don't etch it and make sure it's dry the coating will come off in chunks and plug up the petcock. most tank liner kits come with the proper 3 step chemicals to do the job right. i don't see the need for it on a stock tank, if your tank did rust, a new tank cost less than a sealer kit. good sealer kits are around $40.
