KIT TIP: Wet sanding 

Soak the micro-finishing paper in water overnight 
before use . It will scratch less, and last longer . Al-
ways keep it wet from then on . Using soft cloths, 
or an electric hand-drill with foam polishing pads, 
rub-out the fine wet-sanding scratches to a final 
gloss with medium and fine polishing compounds . 

Use a separate pad for each compound . You can follow this 
with swirl remover if desired . Clean off the residue left by the 
polishes, remove the remaining masking tape from the neck, 
and remove the soundhole masking materials from the body .

Dry-sand the neck and body to a flat, dull sheen with 800-
grit Fre-Cut® paper . Clean the residue from the paper often 
by wiping on a scrap of carpet or a brush . 

“Orange-peel” texture caused by lacquer shrinkage as the 
solvents cure out of the finish should be removed, but don’t 
oversand . When all the little shiny low spots in the lacquer 
have been removed, you’re ready to go to the next step . 

Wet-sand with 1200-grit micro-finishing paper and water, 
to bring the finish to a smooth satin surface that’s ready for 
final polishing . Excess water and residue should be wiped 
off the finish with a clean dry soft cloth as you work . Rinse 
the sandpaper in soapy water often, to remove hard specks 
that can scratch the finish . 

Sanding and rubbing-out the finish 

KIT TIP: Running 

If you get a “run” in the finish, let the surface dry for 
24 hours and level-sand the problem area . If you 
touch wet lacquer, you’ll leave a deep impression 
which will be much more difficult to fix .

Day Three: Lightly scuff-sand the finish with 320-grit paper 
again, and clean off all the residue . You can be slightly more 
aggressive in flattening the sprayed surface now, but be 
careful on the curves of the neck, and on ANY of the edges 
of the neck and body (it’s easy to sand through the edges) . 
Don’t try to sand out all the shiny spots yet . This sanding will 
release solvent from the finish and help it to cure . Let the 
finish dry for two more days . 

Day Six: Once again, spray three wet clear coats, one hour 
apart, on the neck and body . The guitar now has NINE coats . 
Let the finish dry overnight . 

Day Seven: Scuff-sand the finish with 320-grit again . This 
time most of the shiny spots will disappear, leaving a uni-
formly dull look . Spray three more clear coats, one hour 
apart . You now have TWELVE coats . Allow overnight drying . 

Day Eight: Lightly scuff-sand the finish with 600-grit Fre- 
Cut® paper, to help the solvent escape . The neck and body 
should now be left in a warm dry location for TWO WEEKS 
to let the finish harden and shrink . 

KIT TIP: Blushing 

Buy a can of aerosol “blush eraser” for lifting the blu-
ish haze which can occur when moisture is trapped 
in the lacquer finish . Blushing can result from humid 
conditions, or if the coat is sprayed too heavily . 

Stewart-MacDonald’s tool recommendation

Foam Polishing Pads 

Item #3414

Your instrument finishes can have a more professional look when you use these 
fiber-free foam buffing pads . The gentle polishing action helps avoid swirl marks, 
fine scratches and burn-through, leaving a beautiful mirror-gloss surface .
