FUEL - Ethanol Proof Tank Sealers

Fuel Tank Cleaners and Sealers


We have a range of internal and external fuel tank sealers resistant to petrol, diesel, oils, and solvents. All have been tested to be resistant to 100% corn bio ethanol. We have also tested to current E10 fuel with 10% ethanol and the E15 fuel with 15% ethanol anticipated for introduction to the UK soon.

At Rustbuster we use both polyurethane and epoxy technology and our full range includes tank sealers for industrial petro chemical plant bulk storage tanks. Please contact us with your specific requirements. For industrial fuel storage tank coatings, Novalac epoxy and pipe line identification, Shell, BP, and other corporate coating colours please call.

Fuel tanks that require sealing should have any existing/failing coatings removed prior to application.

Slosh Tank Sealer

Our original tank sealing formulation, still ethanol proof and going strong for 30 years now. For bike and car fuel tanks: steel, aluminium and GRP (not plastic).

PC-7 Epoxy Paste

The king of repair paste. It's petrol resistant, so ideal for sealing suspect areas such as seams, welds and pin holes on a tank exterior. PC-7 is a fine paste; not a putty stick.


Epoxy coating for tank exteriors, including sealing of tank seams and repairs after application of PC-7. Stops ethanol/petrol fume bleed that can ruin a painted tank. Over paintable.
