Tank sealant

[LoftCol]

Has anyone used a tank sealant before, the type that you pour in and slosh around the inside. The reason I ask is that I picked a reasonable condition tank, without any dents or filler but a little rusty on the inside. Put the jet washer in and created a few pin holes in it luckily all-in the same place on the underside. I can patch weld it ok, but there could be a few pin holes and thought that fuel tank sealant would be the answer. Any tips, or things to avoid would be greatly appreciated. Cheers

What products are available to you? Normally I would tell you to avoid sealer, but based on the fact that you already have pin holes in it a sealer might be you only alternative. If you could patch weld it and solve your problems that would be the better option. Over the years the seal or not seal has been debated. There are a few that have stated it worked for them and others that have stated that over time it has failed. You have to make sure the tank is properly cleaned and prepped before applying a sealant. You have to also start with a good product. Why I asked what is available to you. I am assuming you are going to have to repaint the tank so saving the existing paint job might not be an issue. I say this because over here years ago with my original tank I brought it to a radiator shop. They actually cleaned it and sealed it. Worked out very well for years until I was able to replace later on with a new tank.

Caswell epoxy would take care of your pinholes. I have two tanks lined with it. It is not solvent based. I expect you must have an epoxy tank liner available to you.

If it's just a couple small holes, you could solder them with a soldering gun, not with open flame unless the tank has absolutely no fuel vapors.

One other note to make is to be sure whatever you choose for sealant that it is ethanol resistant. From what little research I have done evidently most the gas over there contains 10% ethanol much like here in the states.

Resistant to a whole bunch of stuff they put in gasoline. It varies by jurisdiction. Why I choose epoxy.
