| I don't advise using polyurethane. Go with lacquers. Stewart-McDonald
has everything you need but beware that it's pretty involved. Here's an
outline of the process:
take it apart
strip
sand
(stain)
seal
(opaque coat)
clear coat
rub-rub-rub
polish-polish-polish
buff-buff-buff
put it together

| All those steps between "clear coat" & "polish" should be in a "DO
WHILE" loop 'til the thing is right. I've done this before, & I would
*not* recommend it unless you know something about wood finishing. It
might help to practice on a piece of similar type wood first.
(Also, I think the "strip" step refers to the guitar & not you ;-8 !)

| Two more notes to check out are 590.20, and 1454.13.
A few tips:
1. Use nitrocellulous lacquer. This is what manufacturers like
Gibson, Fender, Martin, etc. use. Acrylic lacquer is easier to
use and is quite durable, but it tends to dampen the instrument
and will have an affect on tone and sustain. The best nitrocellulous
lacquer I'm aware of is "Behlen's Qualalacq". It is available from
Stewart MacDonald, as well as other luthier supplies.
2. Most major manufacturers do not use "stain", at least not the
traditional type of wood stain that soaks into the grain of woods.
Most manufacturers use transparent shading lacquer. This is applied
after the initial sealing coats of lacquer. Shading lacquers are
available in several differant colors and can be mixed to achieve
the exact color you want. For example, the back of a Les Paul
is usually a cherry color. This color is made up of 3 parts red,
and 1 part brown shading lacquer. Shading lacquers are also available
from Stewart MacDonald.
If you can provide some more information about the instrument you
wish to refinish and the desired color, I should be able to help
you figure out what you need to do.
Before you decide to take on this project keep in mind that
professional results are achievable, but will take a great deal
of time. Lacquer is extremely volitile. The fumes are quite harmful,
and the slightest spark can cause an explosion in an enclosed room
without proper ventilation. I suggest you do all of the spraying of
lacquer outdoors, or in a very well vented room.
As far as spraying equipment is concerned, you can get "Pre-Val"
aerosol propellants from paint stores for a couple of bucks. These
have a glass bottle and screw-on propellant. These allow you to spray
any liquid you wish without a compressor or spray-gun. For small
jobs like a guitar, these are ideal.

| If I remember correctly, nitrocellulous lacquer is toxic when sprayed
and proper safety gear should be used...

2747.9 | More ramblin...Been sniffin' too much lacquer! | MILKWY::JACQUES | Vintage taste, reissue budget | Thu Jun 10 1993 21:33 | 42 |
| Greg's right. Nitrocellulous lacquer is very toxic. You should use
a mask rated for organic solvents. You can get these at most paint
stores.
There are also many new water-based finishes that are being used
in the musical equipment industry. These are known as hydra-coat
finishes and suppossedly you can get any effect you want including
Sunbursts. These are considered to be much more environmentally
safe to use than lacquers or other oil-based finishes, and are
non-toxic. Stewart Mac sells a full line of hydra coat finishes,
instructional videos for applying it, as well as spraying equipment
that can be adapted for hydra-coats. This is suppossedly the wave
of the future, but I think a nitro-cellulous finish will always
be preferable on a vintage-style instrument.
Many manufacturers these days are offering lower-priced lines
with satin finishes. These are mainly used on flat-top acoustics,
although I've seen lot's of custom basses with exotic wood bodies
that had satin finishes as well. Guild, Takamine, etc. all offer
Satin finished instruments at prices considerably lower than their
high-gloss counterparts. If you've ever done a complete lacquer
finish, you know how much work is involved with water sanding and
buffing out lacquer finishes to get them level. These satin finishes
are applied in 3-4 coats and are not buffed at all. A lot of people
actually prefer satin finishes especially on guitar necks. Fender
applies a satin finish to all guitar necks on "American Standard"
series instruments, Strat+ etc.
I refinished an SG last summer. I talked about the entire process
in note 1454. It's an original style cherry finish. The finish really
came out beautiful.
I drafted a note a while back about guitar refinishing but have
never gotten around to enter it. Perhaps I should enter it here.
I've been looking for another "handi-man special" guitar like the
SG was. I'd love to pick up a Les Paul that needs a new finish and
do it up.

Seriously, I noticed awhile back that Carvin uses tung oil finishes on
their necks. Seems like that'd be a real attractive option for a
do-it-yourselfer 'cause it's easy to apply and would leave a nice satin
finish. Somewhere in the back of my mind, I seem to remember that
former deccie Steve Greve did a tung oil finish on one of his guitars
too. Anyone have any thoughts on the use of tung oil?

2747.11 | ahoy Olive! | RICKS::CALCAGNI | submit to Fred | Fri Jun 11 1993 09:01 | 11 |
| Just one comment on oiled finishes; I have been warned many times by
pros to think carefully about refinishing with tung oil, etc. because
it makes the instrument nearly impossible to redo again. They say you
cannot remove an oil finish the way you can a lacquer or similar and
the oil prevents any overspray from adhering too. Also, if you're one
of those people who believe finish affects tone, oil finishes seep into
the wood more and some say this has a deadening effect on the resonant
properties of the body. Not everyone agress on this though. Bottom
line I guess is, be ready to live with it before you take the plunge.

2747.12 | Oil don't cut it. | VOYAGR::JACQUES | Vintage taste, reissue budget | Fri Jun 11 1993 10:48 | 17 |
| Besides Tung Oil, a lot of people use Watco Danish oil as a complete
finish.
Warmouth will not honor the warrantee on any of their necks or bodies
unless the parts are sealed with a lacquer or a similar sealant. Oil
finishes are not considered adequate protection by Warmouth. I tend
to agree with this believe. Oil eventually dries up and allows the
pores of the wood to absorb moisture. You would have to re-oil the
instrument regularly to prevent it from drying out. The more you do
this, the darker the wood will become. It may also affect glue joints.
If you want a low-gloss finish I would suggest you use semi-gloss lacquer.
This is available in nitro-cellulous form from Behlens, and will
provide permanent protection and a durable finish that will prevent
the wood from being dented or bruised.
