Does anyone know what finish material they use? I wouldn't think it is nitro cellulose lacquer, but I could be wrong. is it polyurethane? I am asking so I will know how best to address a scrape at the bottom of my Uke. UGHHHH!

Contact HMS. They'll know for certain what the finish material is.

at that price point I would be almost certain its poly.

EDIT: that would be for gloss. If its Satin, it can be an oil or sorts I would imagine.

Nitro would be too labor intensive as well as shellac/french polish. The higher end koolaus according to the website our nitro.

Satin could be anything. It's not the type of finish that makes it satin, it's either the amount they put on or they put a matting agent into the finish.

If it is Poly, I suggest "Wipe on Poly". You can buy it at Home Depot or any hardware store in small cans. I use it for everything, including two Ukes I refinished. It comes in gloss or satin finish. I use a piece of old sweat shirt, the outside, not the fuzzy side to wipe it on and let it dry. Very Thin coats as it drys fast (~2 hours). 2-3 coats should cover most finishes. Prepare with 0000 steel wool, no need to sand if it is a shallow scratch. Put the sweat shirt piece in a plastic baggy while you let the coats dry and reuse it for coat 2-3 etc. Wear rubber/nytril gloves and have fun.

Can you take a photo of the scrape?
Is it a gloss or satin finish? Better yet, just give me the type of Pono and I can figure it out.
If the scrape isn't too pronounced you might be able to use Miracle Cloth. I used it for a small scratch on my KoAloha and the scratch disappeared.
But I would need to see what has happened first, so submit a photo please.

According to the F.A.Q. section on the Pono Guitar website (http://ponoguitar.com/faq), they use Polyurethane:


Q: What type of finish do you use? - A: Urethane. We could use Nitrocellulose, and we know that most people have the perception, usually from what they have been told, that Nitrocellulose [is] a "better" finish. But we prefer Polyurethane. This may seem odd, but there is a reason. We do like Nitrocellulose lacquer, but urethane is durable. It does not dent as easy as nitrocellulose, and is not as easily affected by contact with liquids. [...]

Thank you johnson430, I've finally got up enough nerve, and purchased a Miracle Cloth. I had a minor scratch on my Koaloha tenor, the Miracle cloth as advertised performed a miracle. The scratch had been completely removed. The cloth left the area a little dull, I buffed it with a clean white cloth and it buffed up beautifully. Great advice. Thanx again. JJFN

Thanks! I think that is a good thing. Nitro is much more vulnerable to checking.
