If you have never worked with fiberglass there are a few
basic things you should be aware of.

1. When you are cutting into fiberglass, be sure you are
cutting the correct place. Unlike wood, you are not able to
go back and easily fix a mistake.

2. Whenever you are gluing a part to the inside of fiberglass it is
important to roughen the inside surface of the fiberglass with
220-grit sandpaper, then wipe the area with alcohol. The
molding process leaves a waxy residue that can prevent a good
bond between the glue and the parts being glued.

3. If you do not have a high-speed rotary tool such as a
Dremel tool, you should consider purchasing one or
borrowing one from a fellow modeler. This combined with a
fiberglass cut-off wheel is going to be extremely helpful in
the assembly process.

WARNING: The cowl included in this kit is made of
fiberglass, the fibers of which may cause eye, skin and
respiratory tract irritation. Never blow into a part to remove
fiberglass dust, as the dust will blow back into your eyes.
Always wear safety goggles, a particle mask and rubber
gloves when grinding, drilling and sanding fiberglass parts.
Vacuum the parts and the work area thoroughly after
working with fiberglass parts.
