The fuel tank is cut open and any 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 to get rid of all rust. The blasted tank is inspected to make sure that all rust is removed.
Any large holes are closed and badly corroded sheet metal is replaced.
The tank is welded and tested for leaks.
The inner coating is applied by filling it with liquid plastisol and draining all excess fluids. The coating sticks to the shot-blasted surface. The inner coating is white but becomes reddish after the baking process.
The black outer coating layer is applied via rollers and brushes. The black coating is not as smooth as the inner coating, but is more rugged.
Finally, the tank is baked in a curing oven for the chemical process to be completed.
The tank is cut open to thoroughly clean the inside
The tank is resealed with strong welds
Plastisol coatings (both inside and out) protects from rust and chemicals
