    Tank sealer

    Hi, can anyone recommend a good quality fuel sealant, please? I want to use my original 5-gallon fat bob tank but it needs resealing before using. Has anyone recent experience of the products available. Cheers Steve
    I was thinking of using Flowliner tank sealer. Is this a good quality sealer? Or is there better available at a similar price?

    Re: Tank sealer

    Sealed my tank with a great sealant and cleaner kit from frosts. Link below, you can’t go wrong with this kit. Worth paying an extra few pounds.

    Re: Tank sealer

    My local inde, Thunder Bay, recommends getting the tank(s) repaired in a permanent way rather than sealed, tho a perm. repair may be problematic if you're sporting a flash paint job. If I were forced by circumstance to the sealer route I would go with a Mil. Spec. or Aviation grade sealer approved for ethanol ().
    I'm informed that, like paint jobs, sealers fail mostly from surface prep whereat a small area escapes detection only to begat the chain of fail.

    When in danger or in doubt, run in circles scream and shout!

    A common mistake made when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.

    Re: Tank sealer

    Having experienced sealer failure I decided to go down phosphoric acid route. I let it do it’s stuff, hosed it out good and proper then swilled the water out with alcohol - the remaining puddles that are impossible to remove were alcohol rather than water. I left the cap off for a few days and let the alcohol evaporate. Seem ok so far...

    Re: Tank sealer

    Afternoon.

    I've used the Frost system with good results but an experienced builder I know wont use any. He gives the tank a good clean inside and sprays the outside in primer he then rides the bike around for a few weeks and keeps an eye out for leaks. Any leaks are welded.
