ENDURASHNEâ„¢ FINISH WARRANTY

With proper care and cleaning, your EnduraShine parts will continue to look good and keep their high gloss shine for years. Never clean your EnduraShine parts with solvents or carburetor cleaners of any kind. Use of these cleaners will dull the luster and will remove the coating. Never use solvents or carburetor cleaners when rebuilding your EnduraShine carburetor. Do not use paper towels to wipe or clean your EnduraShine parts; always clean your EnduraShine parts using mild soap, water or non solvent cleaners such as Simple Green. Do not use a chrome polish or a scratch remover that is not clear coat safe. For best results, a high quality polish such as Novus No. 2 Fine Scratch Remover, Meguiars or Mothers Plastic Lens Cleaner should be used. Any cleaning product used on your EnduraShine parts MUST be clear coat safe or developed for the cleaning of acrylic coatings. We suggest applying any automotive wax coat after cleaning to help to seal the surface and protect the finish. Use of abrasive or solvent cleaners will void your manufacturer's warranty.
