Using Sealeater is the easiest and most complete way of removing old linings from motorcycle fuel tanks. It works by attacking the chemical bonds of tank linings and allows the complete removal of linings. This is impossible by mechanical means and unlikely with other chemicals. Many motorcycle tanks are lined with poorly designed and poorly installed linings. Poorly designed as they were not meant to cope with fuel containing ethanol and poorly installed as they’ve been applied to tanks with corrosion present. Ethanol dissolves polyester based resins and carries them into the fuel system. As the lining is attacked tanks begin to leak again. For many years motorcycle tanks have been lined with products with a primary purpose of resolving pin hole leaks, bad seams and general seepage.  With leaded fuel this was, if not perfect, satisfactory. With the arrival of ethanol in fuels it has become necessary to protect all tanks from being attacked by the ethanol component itself and the water that it brings into the tank. Ethanol fuel is allowed to contain water and it is also hydroscopic, encouraging atmospheric water to join with it. Ethanol itself attacks aluminium and rubber like compounds. All in all, a joy. Use is simple. Ensure you can make the tank vapour tight. Tip in SealEater and close tank. Check after 2 hours. In that time the simpler liners will have failed and form a sludge to be tipped from the tank. If that is not the case you have a good quality epoxy liner. Seal the tank and leave for 5 days. At that point the liner will be in the liquid either in solution or in flakes. You can pick up and agitate the tank at any time but it does not have a significant affect. Sealeater is a very volatile and energetic compound. If it is being used in a painted tank then care must be taken to avoid Sealeater or its vapours coming into contact with the outside of the tank. Tank exteriors can be protected with two coats of Fertan Conservation Wax aerosol (code 29130) to protect against accidental contact with Sealeater liquid. Sealeater will not remove Tapox 2K liners. NOT to be used in a GRP or FRP fuel tank.
