Post subject:  Storing lacquer?

Hi,
I'm a hobby guitar builder and repair tech.I live in a trailer, and there is limited room. We have a center bedroom that I have converted into a sort of music room/indoor workshop. I have a 2' x 4' bench in what used to be a closet with sliding doors(which I removed) that is used to do "clean" work on guitars, repairs, etc. But recently one end of said bench has acquired a pile of this sort of stuff stacked up. Lacquer, thinner, acetone, preval sprayers. I really need to move this from the bench to make room to actually use it. But I have no room to put it anywhere else in the home.
I have a metal shed outdoors. Will it hurt any of this stuff to move it to the shed?
I'm in Virginia, and it gets cold in the winter here.
Thanks.

Solvent based lacquer, thinners, and acetone should be fine stored outdoors in a metal shed. By all means don't store that stuff in your house. A large metal lockable tool box in some odd corner away from everything else might also be good. I'm not familiar enough with Preval sprayers to offer any advice on that.

Thank you, Clay. The Preval are basically about like a spray can, so I think they'd be fine as well. Much appreciated.

Heat is more of a problem for solvents than cold. The metal shed may not be best for the lacquers especially in conventional paint cans due to large changes in temperature. The "air" inside the can will expand when it gets hot and push the lid open which then will let air into the can and your material will harden or skin over and start to change chemically. At the least you will loose most of the more volatile components of the solvent pack. Screw on top F-type cans like solvents typically come in fair better as the lids cannot be pushed off but the cans themselves will deform and can rupture.
