US STANDARD TANK SEALER

CONTAINS ISOCYANATES

WHO USES FUEL TANK SEALER?

People who restore, rebuild or repair cars, boats, or other vehicles; companies with fuel storage tanks; non-restoration people who have fuel tanks in need of repair.

WHAT ARE SOME TYPICAL PROBLEMS REQUIRING NEED OF SEALER?

• Tanks maybe very rusty inside due to years of non-use.
• Tanks may have gunk or caked sludge inside, which must be removed and the tank walls must then be coated.
• Tanks may have pinhole leaks or leaking seams.
• Tanks may have a combination of the above.

CAN MY TANK BE TREATED WITHOUT HAVING TO REMOVE IT FROM THE CAR?

Usually not. Occasionally a tank will have a small leak on the bottom which can be treated without removal, but this is the exception. Proper fuel tank sealing almost always requires tank removal from the vehicle.

YOU CLAIM US TANK SEALER IS “THE BEST FUEL TANK SEALER MONEY CAN BUY” WHY IS THIS BETTER THAN THE OTHERS?

It’s better because it seals pinholes and seams far better than any other sealer and has great intrinsic film strength, which the others do not have. Its film coating is non-porous, keeping moisture permanently away from metal, and in this way prevents future rusting.

DOES US FUEL TANK SEALER CONTAIN “RUST INHIBITORS” THAT OTHER SEALERS CLAIM TO HAVE?

Any chemical can be called a rust inhibitor, since practically all coatings will stop rust for a short period of time until they are destroyed by moisture or wear and tear. Some types of oil, have been known to inhibit rust for a limited period of time, also. But the only real way to stop rust permanently is to keep moisture away from the metal with a non-porous coating that will get stronger as it is exposed to moisture. Only the US Standard Tank Sealer does this, and that’s why it’s the best product.

HOW MANY TYPES OF FUEL TANK SEALER ARE THERE?

There are two types of tank sealer other than US Tank Sealer, and they are similar to each other in basic structure:

A. PVC type sealer is similar to the adhesive used to seal PVC pipe as used in waste disposal lines, sewer lines, etc. This material is white in colour, coats well, but doesn’t fill holes or seams well because it has poor film strength and is essentially an adhesive rather than a coating. It is highly flammable and has strong ketone vapours which are dangerous to people with heart conditions.

B. PVC type non-curing sealer is yellow in colour and will dissolve in petroleum containing alcohol and other additives, which makes it dangerous to use in ANY fuel tank. Adheres well but never loses its stickiness, and it can easily be scratched off with your fingernail. Contains highly hazardous ketone solvent M.E.K.

WHAT PREPARATION IS REQUIRED BEFORE USING US FUEL TANK SEALER?

If tank contains sludge, gums, varnishes, or rust due to years of neglect or non-use, it should first be cleaned thoroughly with POR 15 Marine Clean to remove all foreign matter. Mix 1 litre of Marine Clean with 1 litre of hot water, put in tank for 24 hours and agitate frequently. Repeat process until tank is clean. Next use POR 15 Metal Ready to etch inside surface of tank and to remove all rust. Next rinse tank thoroughly with water several times to remove all remnant chemicals and let dry. TANK MUST BE COMPLETELY DRY INSIDE BEFORE USING US FUEL.

TANK SEALER.

SHOULD I ALWAYS USE A FUEL TANK SEALER AFTER THOROUGHLY CLEANING OUT MY TANK?

No. Fuel Tank Sealer should be used as a last resort, and is not always necessary. Fuel tanks that are rust-free and have no pinholes or leaks may not need sealing at all. They should however, always be kept full of fuel, which prevents further condensation and further rusting. If vehicles are not used frequently, fuel tanks should be treated with POR 15 Fuel Preservative/Stabiliser, which will keep fuel fresh for more than 2 years and ensure quick starts even after months of non-use.

CAN US FUEL TANK SEALER BE REUSED?

No. Used Fuel Tank Sealer should be discarded because it absorbs moisture from the atmosphere during application and will not adhere properly a second time.

IMPORTANT: US Tank Standard Tank Sealer contains isocyanates therefore use of full breathing gear is advised. We suggest you wear overalls and gloves and cover as much of your skin as possible.
