Some Airstreams have a transparent coating over the bare aluminum to protect the aluminum from oxidation. This coating is known as plasticoat (often incorrectly called "clearcoat"). Eventually, this plasticoat will break down and start to flake off. To prolong the life of your plasticoat, it is important to maintain it by keeping it clean and applying Walbernize. Walbernize RV Super Seal is recommended by Airstream, Inc. for use on trailers with a plasticoat. Quart bottle.
After consultation with the manufacturer of Walbernize and with plasticoat applicators and engineers, we now recommend Walbernize RV Super Seal on Airstream plasticoats (or clearcoats) of all ages. We do not recommend using Walbernize Cleaner, Polish & Glaze on any platicoated trailers because it has a mild grit to it that is not good for the plasticoat. Twice-a-year application will prolong the life of your plasticoat and keep your trailer looking great.
Walbernize RV Super Seal is an original formula containing a combination of cleaning, polishing, and glazing ingredients. It is safe for all types of finishes. RV Super Seal quickly and easily removes traffic film and spots of road oil or tar. It provides an easy cleaning and polishing action while simultaneously depositing a deeply reflective, water-proof, glaze finish. RV Super Seal's glaze finish is long lasting and detergent resistant.
