The fuel tank is cut open and previous coatings and sludge are removed.
Any plastic parts in the tank are removed and replaced with manufactured metal fittings.
Shot blasting is done to give the tank a rough surface and get rid of all rust. The blasted tank is inspected to make sure all rust is removed.
Any large holes are closed and badly corroded sheet metal is replaced.
The tank is welded and tested for leaks.
Inner coating is applied by filling it with the liquid and draining all excess fluids. The coating sticks to the shot-blasted surface. The inner coating is white but becomes reddish after the backing process.
The black outer coating layer is applied via rollers and brushes. The black is not as smooth as the inner coating, but is more rugged.
The tank is then baked in a curing oven for the chemical process to be completed.
