Do not clean vinyl panels using degreasers, caustic alkalis or petroleum-containing solvents. Cleaning should be done using ordinary detergents diluted in water and a soft brush. Clean the panels every time you wash your car.
Once cleaning is complete, apply a high quality silicone vinyl and rubber protectant to the panel to prevent cracking and oxidation.
This compound can also be used to treat body seals, rubber vacuum and hydraulic hoses (which are destroyed over time under the influence of aggressive chemical compounds), as well as tires.
