Why use an internal tank coating?
A problem fuel tank should be replaced with a new one, but as often the case they are usually unobtainable. One solution is to have this professionally repaired by welding new metal into the structure. As a last resort, you can prolong the life of your ageing fuel tank by treating and coating the inside. This forms an inner lining to seal small leaks and to protect the metal structure from rusting.
Most fuel tank coatings have, and will, eventually fail due to the recent introduction of ethanol to fuel. FLOWLINER ARMOUR COAT is resistant against this and alcohol products such as ethanol.
