KIT TIP: Sanding
Always use a backing block or pad when sanding
the guitar body . It will help maintain a level surface .
On round surfaces, use a flexible rubber backing
pad, a thick piece of felt or leather, or fold the
sandpaper three or four times to give it firmness
with flexibility .
Unmask the top, and sand it just as you did the back and
sides . Don’t use the same sandpaper you used on the rest
of the body . Blow-off and vacuum the dust from the open
grain pores .
We recommend finishing the neck and body separately,
for a better job of sanding and buffing . When the neck is
attached, it’s more difficult to fill the grain, sand, and buff
around the neck/body joint . Also, lacquer tends to build up
in that area, and unsightly air bubbles may become trapped
there .
The quality of your finish work is certainly important to the
appearance of your guitar . A thin “nonprofessional” finish
won’t necessarily harm the sound of your guitar, however .
If the following instructions seem beyond your skills (we
assure you they’re not), or to be more work than you’d
like, you can simply apply a low-gloss “wipe-on” finish by
hand, consisting of a couple of coats of waterbase lacquer
or freshly mixed shellac . This will seal the wood and protect
it from the elements, and you’ll be playing your new guitar
a lot sooner .
The following instructions, for spraying an aerosol nitro-
cellulose lacquer finish, are relatively foolproof and don’t
involve an investment in shop spraying equipment . Aerosol
lacquers require no thinner, or course, but it’s nice to have
thinner around for cleanup . Feel free to apply the finish of
your choice, however, according to the manufacturer’s di-
rections . If you decide to use spray equipment, always thin
nitrocellulose lacquers with nitrocellulose thinner only .
KIT TIP: Aerosol Lacquers
Aerosol lacquers have a tendency to “spit” if the
spray tip gets clogged . Wipe the tip clean often .
Also, you can clean the tip by turning the can upside
down and spraying until the spray stream stops . We
recommended doing this each time you are done
spraying, to keep the tip clean .
There are many gallons of finishing information in our book
Guitar Finishing Step-By-Step , and we know of many custom-
ers who are glad they studied the book before finishing their
first guitar . In brief though, here are some pointers and a
finishing schedule to follow .
KIT TIP: Finishing
ALWAYS practice on scrap wood until a finishing
method has been perfected . Scraps of wood are
included in each kit so you can practice all the fin-
ishing steps . If you’d like your guitar to look as good
as it sounds and plays, DON’T RUSH!

Introduction to finishing and materials
All the wood surfaces should be fine sanded up to 220-grit
using Fre-Cut® paper on a sanding block . Start by sanding
the back and sides . Mask the soundboard with brown paper
and masking tape, to protect it from the darker wood dust .
The sandpaper should be no coarser than 150-grit, and you
should switch quickly to 220-grit . Sand in the direction of
the grain, not across it . After the first 220-grit sanding,
dampen the entire surface lightly with a water-dampened
(not soaked!) cloth to raise the grain . Let it dry, and sand
again with 220-grit . Blow-off and vacuum the wood dust .
