Red-Kote is a flexible polymer fuel tank liner that seals pinhole leaks and stops further rusting. Lined on more than 1 million vehicles since 1985, with fewer than 200 reported issues — every one traceable to application error, not the coating itself. Designed for gasoline tanks on motorcycles, cars, and trucks. Limited applications with aviation gasoline, diesel fuel, and some racing fuels. Biodiesel, racing fuels, and methanol-containing additives should be tested before use. Red-Kote seals the small leaks that often form along seams and where straps wrap around the tank. It also seals light rust under the coating so it cannot flake off to plug fuel-line filters or cause engine damage, and prevents further rusting by keeping condensation away from the metal. What makes Red-Kote different Stays flexible. The coating won’t crack as some others do. Tanks coated in 1984 are still doing well. Tight adhesion. Won’t peel off even when the metal is bent — protects against loosening from vibration or denting. Methanol tolerant. Unaffected by up to 10% methanol. Above 10% may leach the red dye but the coating remains tightly bonded. Ethanol tolerant. Works fine with E10 through E50. Performs well in long-term E85 testing. Not recommended above E85. Faster drying. Dries faster than many other sealers. Thinning with acetone and applying two thin coats reduces time further. Levels well. No wide variation in thickness as with some other coatings. One-coat coverage. Usually only one coat needed. Holes up to 1/32" (1 mm) can be coated and sealed safely. Bright red color. Easily visible so you can be sure you didn’t miss a spot. Packaging Available in one-quart metal cans packed nine per case, or one-gallon metal cans packed one per case. Backed by Damon’s guarantee and over 70 years of service to the automotive industry.
