Sealing Gas Tanks

[Goldenrod]

I've used this product on alot of BSA tanks . It's a thick epoxy .

Gas Tank Sealer - Caswell Inc

This works well after other sealants failed.

I've tried most, but POR 15 is the best that I have found.

I have used several different sealers, and Caswell is my "go to." The preparation is the most important step. Get it as clean as you possibly can. We sealed a 1973 Yamaha 80cc tank, ind it's still going strong about 5 years later.

By the way, Caswell is now back in stock. I just bought some more for a set of custom tanks.

I’d look for someone that’s repairing model A and T tanks military tanks etc the guy I was using for old HD tanks would soak them then coat the inside then bake them. I still have a pair of fatbobs that hasn’t separated. The island schwinn guy is right using some of these coatings work for period of time then cutting a tank in half is expensive. Plus finding that guy is harder than finding a different tank. I’d look in a hemmings motor news and maybe find a shop that specializes in just tank repair good luck

I just sealed my Simplex Servicycle gas tank. Went well. Gotta slosh it around fast to get good coverage.

I used Red Kote on many projects. Used this stuff on my gas tank in my 67 Ford truck and many other projects. Follow the directions and you’ll be happy. This stuff really works great.

Thanks all!! I have a tank that’s going to need coating. It’s leaking around one of the bunges when putting a external gas gauge was the thing to do. The guy I once knew that repaired tanks has retired so I’m going to try the red kote product. I have somewhere some of the two part stuff I bought last century from the bike shop that I hope my nephew took off my shelf and tried using because that’s the junk crap stuff that works for a summer. I can just imagine what that slime does to a carb. Thanks!

For the e-bike owners if you dip the battery in this stuff your battery will never catch on 🔥

I would think there is a better chance of catching fire, or at least deterioration of it because it won't be able to dissipate heat as well with the coating.
