2K finishing schedule

[moobox]

Hello all
A friend of mine finishes electic guitar bodies and necks with 2K auto paint. Is this stuff OK for acoustic instruments? He reckons it should be but I dont see or hear of anyone finishing acoustic guitars or ukeleles with it. Anyone know of a decent schedule for doing a burst (on an acoustic guitar) with 2K?

Thanks - Ed

I never used it. Can't help on this

I've never used it either. I would think that an auto paint would probably go on a bit too heavy for an acoustic guitar, but again, I don't know this specific product, so I can't say for sure.

The ideal acoustic guitar finish is as thin and light as possible and still protecting the instrument.

I'm unfamiliar with it's properties as well. Before deciding to use it or not, do some investigating and determine how it holds up to flexing. The soundboard/back move a lot and something that cures too hard may crack. You can get by with more on a solidbody electric than you can on an acoustic.

Taylor uses a UV cure polyester so anything can work. IMHO though a catalyzed urethane is a great finish for an electric rock guitar but I would not use it on an acoustic. For one the product was not engineered to be used over wood, it was meant to be used on metal auto body's. While it works on larger, thicker pieces of wood, the thinner sections used on an acoustic behave differently. They expand and contract more, they are after all open to air inside the box. An electric is completely sealed and does not react as quickly to changes in RH. The manufacturer also makes no type of sealer for wood, so will the product self seal? will in adhere to the sealer you choose satisfactorily? These are important things to consider, just as important as impact on actual tone.
