REFLECTOR: Perma-grit

[David Ullman]

I don't like Perma-grit very much.  It gets dull with all the sanding you
will be doing.

Instead of the perma-grit, just use a very flat, straight grained piece of
wood of any length you want.  I actually used a piece of old 2x4.  Then go
to the auto supply store and buy 30 grit paper with adhesive on the back.
It comes 3" wide (or there abouts).  You can and should buy a whole box of
it, you will need it.  This way you always have a very coarse , fresh
sanding tool.  Mine worked great.  I had "fast build" wings that came with
primer on them, but they were no where near flat.  I sanded off everything
put on at the factory, filled in the valleys and now I have very good
surfaces.
