Polyurathane On Acoustic Guitars

[dumbassbob]

I finally bought a acoustic.Its a good midprice guitar made with a mahogany top.But now that Ive had it for a month I notice that it some times sounds a little muffled,would removeing the poly coat finnish and spraying it with Nitro lacq.make it sound better.

Is it polyurethane or polyester? Also, how do you know what it's been finished with?

The only problem with some of these finishes is they are sprayed on too thick. There's nothing really bad about either finish. Polyester can be very hard to remove, and is usually the shiny plastic looking finish you see on cheap imports. It's a two part catalyzed finish.

Polyurethane is not so bad and is used on some expensive instruments, like Alembic.

I doubt it's the finish though, otherwise it would effect the guitar's tone all the time, not just sometimes.

Have you changed the strings?

If you have the equipment to spray lacquer it couldn't hurt, but it is a lot of work to do a refin, and might be more than the guitar's worth.

Poly Refinish Carvin

The guitar is a Carvin C350 Mahogany top list for $900.00 sell for $400 I tryed to burn it with a ciggerett and it went out before even leaveing NO mark.There well made for the $$ but I think to keep cost of repairs down,they cover them in this bowling Ball Floor crap.

Don't do it! If you are not an expert refinisher you will ruin the guitar. If you don't like the way it sounds and you've tried a few different sets of strings, Sell it and get one you like.
