Great Planes Extra 300S 60 Kit - GPMA0236 - Manual (Page 40)

Cover the model with Top Flite MonoKote Film using the
recommended covering sequence that follows. Before you
cover the fuselage, first apply 1/4" wide strips of MonoKote
film in the corners of the stab and fuse and the fin and the
fuse. Then, proceed to cover the fin and stab with pre-cut
pieces that meet in the corners and overlap the 1/4" strips.
Never cut the covering on the stab and fin after it has
been applied except around the leading and trailing
edges at the tips. Modelers who do this may cut through
the covering and into the stab or fin. This will weaken the
structure to a point where it may fail during flight.
Since the tips of the elevators and stab are squared off it is
easiest to cover the tips before you cover the tops and
bottoms. Do the same for the fin, rudder and the wing.
Some modelers drill a small hole in each stab rib and the
trailing edge of the stab to allow expanded gas to exit while
heating the MonoKote film. This keeps the covering from
“ballooning” and allows you to securely bond it to the entire
stab. The same thing can be done with the elevators, fin
and rudder.
When you cover the fuselage, use your covering iron to
seal only the top of the turtle deck in the center, and the
bottom of the fuse. Use your heat gun to shrink the rest of
the covering on the fuselage–especially near the side
stringers. This will provide a realistic, smooth transition
from the turtle deck, over the side stringers, down to the
fuse bottom.
Since the ailerons are long “strip” ailerons some modelers
prefer to cover the top and bottom with one strip of
MonoKote film by covering the bottom first, then wrapping it
around the leading edge over the top.

After the model is covered, use fuelproof model paint,
30-minute epoxy thinned with alcohol or finishing resin to
coat areas that may be exposed to raw fuel or exhaust
residue. These are areas such as the firewall, front and
back of the belly pan, fuse openings for the wing and fuse
doubler, fuel compartment hatch and the fuse top forward
of the sheeting.
Top Flite LustreKote ™ fuelproof paint is recommended for
painting all the ABS plastic parts and the aluminum landing
gear. The wheel pants should be removed from the landing
gear for painting. Use a file to round the corners of the
aluminum landing gear before you paint it. At least one coat
of LustreKote primer is highly recommended to fill all the
small scratches left from sanding as well as small pin holes
in the Bondo filler. Wet sand between coats with 400-grit
sandpaper and apply a second coat of primer if necessary.
If the parts are primed properly, only one coat of color
should be required.
Before painting the canopy, use scissors or a hobby knife to
trim it along the molded-in cut lines, then true the edges
with your bar sander and 220-grit sandpaper. Use 400-grit
sandpaper to scuff the frame portion of the canopy so the
paint will stick. We recommend you paint the canopy frame
with Pactra
® Formula-U or Chevron ® Perfect Paint. Use
masking tape to cover the portion of the canopy that is not
to be painted. If you are not sure that the paint is
