Recommendations
With fiberglass, lightly sand the rocket with
240-400 grit paper, prime and sand.
Paint with a good quality paint like Krylon or
an auto engine paint that will withstand the heat
created by the friction during flight.
Finishing with Magnaframe
Protect the Rocket from Zippering.
Zippering is when the ejection charge is too
great and the impact of the airframe and the
shock cord is so violent that the shock cord liter-
ally rips or zips the airframe. To strengthen the
Magnaframe airframe and reduce the potential
for zippering you can place a small amount of
cyanoacrylate (super glue) on the Forward
½
”
to 1” of the airframe. Spread the glue on the
outside, inside and edge of the airframe end and
let it set completely. Obtain from your local
hardware store some DAP
Plastic Wood. It doesn't mat-
ter the color. Prime the phe-
nolic airframe with extra thick
filler spray primer. With a
gloved finger, extrude a small amount of the
DAP Plastic Wood and trace the fine grooves of
the Phenolic Airframe and deposit the DAP
Plastic Wood into the groves. Be consrervitive
because all that is not in the grove must be
sanded away. That said, the material does
shrink a bit as it drys, so it must be left a little
high. When the DAP Plastic Wood is com-
pletely set up, sand the airframe to a smooth fin-
ish.
