blade.
7) Remember what said about the sanding? Well it
starts here. Using 180 grit sandpaper, sand the edges,
top, bottom, sides, etc...

Sand through any bubbles or wrinkles in the laminated
fiberglass. Replace the sandpaper often, CA laminated
glass will dull sandpaper quickly. While it's important
to smooth the surface out, don't smooth it all out
during this step, there will be plenty of opportunity to
sand later too.

Wear that dusk mask while sanding.

9) Brush on at least 2 thick coats of primer onto the
surface. Don't be shy here, lay that primer on nice
and thick.

 

10) Sand down the primer you applied in step 9.

The mottled appearance you see is a result the
high spots sanded down, and the low spots filled in
with primer.

If you can still see lots fiberglass weave showing
through, go back to step 9 and apply some more
primer.

11) Apply spot putty over any areas that has pin-holes,
or patches of fiberglass weave is still showing through.

12) With the spot putty applied, it's time to sand again.
Using 220 grit sandpaper, sand down the areas where
the spot filler is applied, and give the entire surface
some additional sanding too.

13) Now that you've sanded everything down, and all the parts look smooth or as smooth as it's going to get
(you should thoroughly tired of sanding at this point, and about ready to throw the whole thing in the
fireplace, but wait, you almost finished). Use traditional painting techniques from this point forward.

Here's a summary of painting:

- Spray on a heavy coat of primer
- Sand the primer with 320 grit sandpaper
- Fill any imperfections with spot putty (you shouldn't have many at this point)
- Spray on a light coat of primer
- Sand the primer with 400 grit sandpaper
- Spray on the paint (your choice of colors, and type of paint, but it should be fuel proof)
