GLUE AND ADHESIVES
CA (Cyanoacrylate):
This is for general-purpose construction when gluing wood to wood,
metal to plastic, or wood to plastic. It is the ONLY glue to use when attaching the Expanded PVC to either wood
or to itself. We recommend using gap-filling (medium) CA cement. When using the gap-filling (Medium) CA,
hold the parts together at least 15 seconds. Use with caution since it will bond skin instantly to your work in
progress
.
CA Accelerator
:
This is sometimes used along with the CA adhesives to “kick off” the CA
cement. Generally, if your CA is fresh, you won’t need it too much unless you are in a hurry, but if the cement
has gotten old, then the accelerator is almost mandatory.
Epoxy:
This is sometimes used as a substitute for the CA adhesives. Generally, use epoxy to
build the basic wooden frame, and when attaching the deck fittings. DO NOT USE EPOXY ON YOUR PT-212.
Liquid Plastic Cement:
This is used to cement styrene plastic-to-styrene plastic. It will
not work with the Expanded PVC.
PAINTING
There is an old adage in the Navy that warns recruits to salute everything they see, if it
doesn’t return your salute, paint it gray! Well, just about everything on the PT boat is painted gray.
Even the horizontal surfaces are painted gray. To eliminate fish eyes, oils, and dirt, wipe parts with
rubbing alcohol on a clean rag before spray painting.
Painting Tip: I painted all of the major assemblies separate before they were glued to the
deck to get into the hard to reach places. After the major assemblies were cemented to the deck,
then I painted the deck/hull. This way, I was guaranteed a good gluing surface between the deck
and the part. The smaller parts like the Hatches, Vents, and Fuel Caps were all cemented to the
Deck first, then painted. Suggested colors are listed below:
