FINISHING YOUR ROCKET
Apply sanding sealer to fins. When sealer is dry, lightly sand parts.
Repeat sanding and sealing until balsa grain lines are filled. Optional:
Spray a light coat of automotive primer over entire rocket. Lightly sand
(600 grit) when primer is dry. This allows the paint to adhere better and
gives a smoother finish.
Spray paint the entire rocket gloss white. Follow instructions on spray
can for best results. Allow paint to dry overnight before applying decals.
Refer to photo on front of instructions and photo on panel for decal
placement. To apply decals, cut out each decal, dip in lukewarm water
for 20 seconds, and hold until it uncurls. Slip decal off backing sheets
and onto model. Blot away excess water. For a more realistic appearance
and to protect decals, spray a flat clear coat on the rocket.
