The lower part of the aircraft is painted with ultra gloss polyurethane. The forward upper
glare shield part is painted with flat black polyurethane. The fuselage frame is painted
with a primer, and then painted with a gray ultrathane.
All repairs involving refinishing should be painted to the original specifications. The
following procedures should be carried out step by step.
A. Sand part to bare metal using 180 grit paper or finer. Avoid removal of cladding
with the Alclad parts, whenever possible.
B. Thoroughly clean area with isopropyl alcohol, a solvent, or thinner. Allow time to
dry.
C. Apply one thin spray coat of Epoxy primer with Epoxy hardener. Allow time to dry.
D. Mix the required quantity of Polyurethane (follow the directions on the can) with
the prescribed amount of activator. Spray a smooth and even coat directly onto
the primed surfaces. Apply at least two coats and allow time for drying between
the coats.
Certain chemicals cannot be removed effectively by
detergent solutions. Special cleaning agents are
available for that purpose. It is suggested that the
chemical suppliers be contacted for cleaning
agents that are suitable for those special needs.
A regular and thorough cleaning of both the interior and exterior of the aircraft is a major
part of corrosion control. All areas of the aircraft are accessible for cleaning by removal of
the panels. The cleaning procedure that follows is recommended for general purposes.
