Sealing and Finishing with DEFT
☐
Seal the grain! The plywood bottom requires
little sealing of the grain, in-fact, just a few
coats of DEFT lacquer spray will smooth it out
nicely. The top and sides of hull, however,
will benefit greatly from a couple of thin coats
of sanding sealer. I suggest you make your
own sealer from a mixture of equal amounts
(by volume) of DEFT brushing lacquer and
talc (baby powder) creating a pancake batter
like mix. Apply an even coat of sanding
sealer exterior surface of hull allowing to dry
(about 30 min) before sanding smooth with
400 grit paper. Apply sealer in same fashion
to vertical fin (rudder), battery hatch, and
motor mount. Repeat process at least once.
☐
Now coat hull, hatch cover, motor mount, and
vertical fin with at least two coats of DEFT
clear lacquer spray, allow to dry, then add
your color scheme from a compatible lacquer
based paint. Follow up color spray with at
least 3 coats of DEFT.
Notes: Sand lightly
with 600 grit paper between applications of
lacquer. When applying each coat of lacquer
do not forget to seal the interior of the access
hatches. Additionally, don’t forget to seal the
inside of the motor mount.
Final Assembly
☐
Apply self-stick gasket material to top of hull
matching pre-drilled holes in gasket to those
in the hull. Tip: It will be easier to position the
gasket if you, initially, only remove a corner of
the backing paper, position the gasket, then
remove the rest of the backing paper as the
gasket is set into final position.
☐
Install rubber rudder post bushing with
flanged base 13/16” from end of 2-3/4”. length
of 3/32” diameter wire.
☐
Now, install rudder post with bushing seated
against deck top. Retain with CA glue.
