Directions
Before: If the tank has old failed sealer or coating inside, it should be removed with a coating stripping agent or sandblasting before starting the repair process.

Step 1: Mix 1 quart Bill Hirsch Cleaner Degreaser with 1 quart of hot water. This solution will be used to remove any gum, varnish or sludge from the inside of the tank. Drain.

Step 2: Pour the entire bottle of Bill Hirsch Tank Etch to dissolve rust, coat the tank with zinc phosphate, and etch the metal for better adhesion of the sealer.

Step 3: After the tank is clean, drain the tank and rinse thoroughly with water. Let the tank dry. When totally dry, pour in the entire can of Bill Hirsch Tank Sealer.

Step 4: After all surfaces have been coated, drain the tank for about an hour to remove excess sealer from the tank.
