Note: Prepare all parts separately and paint separately.
2.
Completely sand all outside surface area with 150 grit to give paint adhesion. The
factory uses a Random Orbital Sander and 150mm Stickit discs.
Note: Ensure that glass is not cut into in the sanding process
3.
Grind excess resin from joints being careful not to grind into fiberglass layers. Take
care not to grind into the horn of any control surfaces.
4.
A clean wire brush is used to search out any crab holes or pinholes. Give the entire
aircraft a good scrub all over especially around corners etc.
5.
Wear a breathing respirator with painting cartridges right from initial sanding
through to painting.
Hint: Body Filler sets quickly in high temperatures particularly when larger mixes are
necessary. Use cold packs under the Body Filler board to extend setting time.
6.
Follow instructions carefully and experiment with setting times.
7.
On large radius (e.g. sides of fuselage) an extra large homemade spatula (9” thin
tin plate) is very handy when applying Body Filler.
8.
When filling up to window edges, grind chamfer onto edge of window to give depth
for bog adhesion.
WARNING
THE GEL COAT IS MICRO THIN, SO SANDING IS ALWAYS A CAREFUL
PROCEDURE. IF GEL COAT IS INADVERTENTLY PENETRATED DO NOT CONTINUE
SANDING INTO STRUCTURAL GLASS.
9.
With the surface satisfactorily prepared white primer is required only on the
discolored areas (i.e. Body Filled areas). Pin holes become evident after the primer
is applied so use “spot putty” to fill. Be careful and meticulous to find all pin holes
because primer and top coat will not fill holes.
10.
Your final product can only be as good as your preparation. Remember, paint does
NOT cover a multitude of sins.
11.
The factory uses a low-pressure pot gun for spraying at pressures from 60-100 psi.
12.
It is mandatory that exterior color is WHITE only broken if desired, by pin strips on
the vertical surfaces (i.e. Sides of fuselage) but not horizontal surfaces (i.e. top of
wings or fuselage) as the heat build up under the tape in hot sun is considerable.
13.
After filling all pinholes spray another coat of primer on the discolored areas. An all
over primer coat is not required over the gel coat as gel coat is a sufficient
undercoat.
