All of our tanks sealers work in Fibreglass Fuel Tanks, you have a choice of size either Mini Kit for fuel tanks up to 15 Litres, and Fuel Tanks up to 33 Litres, with a variety o colours on the larger kits.

If the tank is new, and the inside is smooth, puts some screws in and shake it to make surface rough, if its already rough, then leave as is.

Wash the fuel tank out using hot water and a dish washer tablet, then you are good to start on the sealing.
