Ahmed Flamenco -> which paint? (Sep. 9 2016 13:08:01)

guys I want a to paint a guitar with yellow without hiding the grain then polish it with polyurethane or even if I want to paint it with dark orange,what paint should I use?

For uniformity color is normally added to the finish rather than applied to the raw wood. I don't know which tint works best in polyurethane but you can easily find out with a net search.

Epoxy or elastomeric [:D] haha
Do people really put polyurethane on guitars??? I hate that stuff.....

When you say paint do you literally mean paint? The implication of paint is that it will be opaque and not show anything under it.

You might be looking for a toner or dye. Dye can be applied directly to wood in order to change the color. It is transparent and merely deposits tiny pigment particles on the wood allowing the wood to show through.

Toner (or some dyes) can be mixed with a clear finish thus giving the clearcoat a tint. This is usually done with lacquer, shellac, and some catalyzed finishes. If you were to strip the lacquer away, the wood would be its natural color.

Transtint is my dye of choice. It can be added to lacquer, shellac, or water based finishes. I believe it can be added to oil based poly as well:

quote:

"TransTint Dyes can be added to some oil-based products. The dye can be added directly to linseed or pure tung oil. To add to oil based varnishes mix 1 part dye with 4 parts acetone before adding to the finish. Do not exceed 2 oz. of this mixture per quart. Shake solution thoroughly before applying to wood. TransTints cannot be added to most of the “Danish” oils or finishes thinned with a high ratio of mineral spirits."


Another option is to do a semi transparent finish. I see this mostly with electric guitars where the grain underneath shows through partly and the finish is a few thin coats of colored lacquer (paint) which looks pretty swanky.

You know some of the modern polyurethanes are quit good, for one, Taylor Made guitars has done extensive research into it, to see about sound characteristics, and found it doesn't
really make any difference, and one plus is that it is much more durable and lasting then lacquer finishes. I really feel that from the old days lacquers where used, thinking the sound would reverberate from the wood better,
I think in these modern days, the finishes are very good, but really it's up to the guitar maker to have the final decision. Old traditions are hard to break. If you have any more data on it then Taylor made has, please let us know.

I don't, I'm speaking from a building industry background(general contractor). The Polyurethanes I tend to see are super thick glopy messes that get put down on floors. It's easy to imagine it could be reformulated to something thinner to work for guitars. Then again, steel strings can push a lot harder than nylon, can they really get that delicate?
