EXTERIOR WALL MAINTENANCE
Aluminum Sidewalls
If your RV has aluminum walls, the exterior surface has a baked-on
enamel paint finish with vinyl decals. When clean, (see
recommendations for washing above) and at least once a year, the
exterior surface should be waxed with an automotive style wax.
Work in the shade, applying wax to small areas with a damp cloth
or sponge. When dry, buff the wax with a clean soft cloth.
Fiberglass Sidewalls and Painted Surfaces
If your RV has laminated walls, the exterior surface is a
combination of fiberglass, paint and vinyl decals. When clean, (see
recommendations above), the exterior surface should be waxed
using a marine type wax on the unpainted portions of the coach.
Marine wax is best suited for fiberglass surfaces. Regular
automotive wax is suitable for painted surfaces of the RV. Work in
the shade, applying wax to small areas with a damp cloth or
sponge. When dry, buff the wax with a clean soft cloth.
Reduce Sun Fading
Avoid storing your RV in the same spot facing the same direction
for extended periods of time. The sun can literally bake the finish
off of your RV if it is not properly rotated during prolonged use and/
or storage.
Sidewall Trim and Component Sealants
Check all sealants when washing or at least two (2) times a year,
whichever is more frequent. In warmer climates some normal
expansion of the aluminum siding may occur, causing slight
protrusions of the skin. Do not attempt to press down on the skin to
correct this normal condition.
Other areas that will need attention include the moldings used on
the side walls and the compartment door edge moldings. Since
these areas are more accessible for periodical checks, It is
recommended to inspect the side walls and compartment doors
every time you wash your vehicle. Sometimes washing the side
walls can actually remove loose sealants that should be replaced.
If you find an area on your side walls that needs to be resealed, a
clear silicone, or one that matches the color of your side walls
should be used. When resealing compartment doors, only a clear
silicone sealant is recommended, as these doors are usually
painted and the color would be difficult to match.
