I have an unused & unopened Eastwood's Gas Tank Sealer & Etching kit gathering
dust that is available for cheap plus postage, if anyone is interested.
> Once the tanks are out I recommend the following.. Wash out each tank
> completely after fully disassembly (ie tubes hoses, breather lines, sending
> units... if you have some lacquer thinner, wash that around in there too.
> then let them dry. Once they are dried, EVERYTHING that is in side the tank
> needs to be removed, and an easy way to do this is with a good couple of
> handfuls of clean nuts bolts, nails, even crashed gravels works well for
> this. put a cup or two in the tank, and tap off all openings (make sure
> there is NO gas smell in them at all. No go sit in your favorite chair and
> watch football, or the All-star game..(Here at Safeco Field !!...Sorry
> Shameless plug for our stadium and Mariners!) Start shaking this mix around
> in the tank. Makes a lot of noise, the more violently you can shake it the
> better and less time it takes. The abrasives in there will chip and grand
> away at the paint, and do no damage to the tank itself. when done, remove
> the tape and dumps the stuff.out. The tank should now be pretty clean and
> shinny on the inside You're half done....
> No call around to your local motorcycle dealers and ask for Kreme It's a 3
> step solution.. Cleaner, Prep, and sealant...this one's not cheap and
> you'll need probably two full kits @ $39 each....Since motorcycle tanks
> Never have paint in them, the cleaner may not remove the paint. That's why

> affected by any fuels, including Av-gas (high octane Aviation gas), alcohol,
> nitro (Dragster fuel), or anything else we ever ran through them. For the
> cars, just regular gas and alcohol are the main ones.. Now.. Rinse out the
> tanks one last time to remove that last of the grit, and chips.. and let
> them dry. A Hair dryer works well for this. Follow the instruction now on
> the sealer you bought, Once this stuff has been washed all around inside the
> tank, it adheres to everything, and seals all liquids away from the metal.
> Sealing all rust, pin holes, cracks, leaks, and in this case flaking paint
> from ever entering the fuel system again. It take a full day for this stuff
> to cure, but it works like a charm...this is how I did my tanks, on both my
> old Alpine, and several motorcycles over the years...
> Hope this Helps
> Good Luck.!!!
