I have a 1971 Commando and have refurbed my tank. Go on the web and look up Red White and Blue tank liner. He is based in Tasmania Australia. It is brilliant and widely used over here. Can be used in steel and fibreglass tanks. Obviously no need for the rust eliminator in the kit with a fibreglass tank. To clean the tank out you use a mixture of warm water and "Napisan" (Australian nappy/daiper soaker) let it dry out then mix the 2 pack product and pour into the tank and swill it all around the tank. Full instructions come with the pack Have a look at it.

You can try GTL Advantage in North Hollywood CA. They specialize in MC gas tanks.
Or, when I did it myself, I used the Caswell product.

So far so good in both cases. However, I have not been running any ethanol fuel since lining the tanks.

The challenge with sealing a glass tank will be proper surface prep of the polyester material that has been contaminated with fuels and potentially softened by ethanol. in the boating industry when needing to prep a polyester hull for repair or refinishing, acetone is usually put to use on unpainted areas. It will not dissolve the surface but does remove many organic contaminates. It can later be washed out with water based soap quite easily.
Inner surface should then be ready for further prep with sealer of choice.

I've had an aftermarket (Burton Bike Bits) fiberglass tank on my fastback since 08 and I just use "normal' gas from the pump - no effort to avoid ethanol or any special storage - I just put Stabil in the fuel as I do for any vehicle that will sit for several months. I treated the tank with Caswell before its first filling. Don't know whether the Caswells made the difference or it is the "ethanol-resistant" resin used in the manufacturing process but it's as hard/firm/leakfree now as it was when installed.
