Lew,
Does that mean that a Nitro finished guitar can give of poisonous fumes??
Lacquer thinner is toxic as heck and that's why conventianal lacquers aren't used by any of the big companies any longer. It's like sniffing glue and harmful to your brain cells and nervous system. It's worst when it's being sprayed and when the finish is still wet. After the finish is dry to touch, it still takes months and months to get as hard as going to get...during that time the finish is still out-gassing, but only someone with chemical sensitivity problems would probably be affected. There are alot of people like that tho...people who get a headache or get sick from a new finish or new car smell.
The primary reason why Nitro is not used any longer by major builders is due the EPA regulations. All Companies must have proper ventalation, and hazardous waste removal in place and it needs to be proved in the event a inspection is requested by the state in where the guitars are being made. Violations of state EPA laws can be very expensive. The MSDS (material saftey data sheets) on Nitro reads very bad, and only small builders are using this today. Unfortunatley IMO it offers the best finish of all the materials being used.
