Default Bare spots in finish

I have this old Yamaha FG-110 (orange label) that I just replaced the rusty head assembly with heads from another useless guitar I had, and I re-glued the pick guard. This is my "camping guitar". It goes on wilderness canoe trips with me. I put old strings on it, because I don't want to spend any money on it. It has some pick wear spots on the top before and after the pick guard. This guitar gets rained on sometimes so I was wondering if I should seal up the bare wood on the top, and what should I use? I've heard lacquer, shellac, Tung oil, polyurethane (but I heard strange problems with using that, like it will soon chip off). But all the advice I'm looking at are all in the context of refinishing an entire guitar or for repairing electric guitars and all that are actually worth something.

What's a good treatment, if any, that I don't have to spend much money on. I do have cans of polyurethane in my basement.

Personally, I'd just brush a bit of shellac onto the bare spots to keep them sealed, and leave it at that -

Yeah, I'd also go for shellac, but I'd do four or five thin costs.
If you want a little more protection, a couple of coats of TruOil would also work.
Another alternative would be to flood the bare spots with superglue.

Hmmm. I'd probably go to the dollar store and buy a stick-on sheet of clear plastic, such as used to protect the face of an iPad. I'd cut it to shape and stick it on. It will prevent further erosion of the wood while making it resistant to water. Shellac is only so-so in its resistance to water.

By not applying a finishing material, you don't risk making a mess of it, in the event you aren't experienced in applying gloss finishing materials.

CA glue may discolour the top and is permanent. However, if you don't care about appearance, any of the options is adequate, including leaving it alone, on a guitar you state is not worth even putting new strings on it.

I wouldn't do anything. It's a laminated top, which is pretty durable.

What is the original finish? Is it lacquer? Wouldn't that make the most sense instead of doing different things, like shellac, or TruOil?

Don't play it in the rain.

Just touch it up with Poly since you already have it.


Its not a big deal either way since its going to be abused.


Little wipe on poly on the exposed wood and your fine. Turn it over in the rain so water doesn't get in the sound hole or on bridge.

It was a poly finish originally.

Truoil is just easy, but it would take more coats to protect then poly.

Don't use lacquer.

Shellac would work if it was all you had
