With the introduction of alcohol or methanol into gasoline, we have formulated a new gas tank sealer which resists most gasoline additives.

Seals pin holes and leaking seams. Keeps rust and scale out of fuel lines and filters in all steel, cast iron, and aluminum fuel tanks. Prevents deterioration of old and new tanks. Not affected by gasoline, kerosene or Diesel fuel. Simply shake loose rust and scale out of tank, pour in my sealer, rotate tank to evenly coat all surfaces. Pour excess sealer back into can for reuse. Seals carburetor and gas tank floats too. No etch or expensive preparation necessary.
