A friend of mine recently learned a hard lesson. I thought most folks knew that any kind of bug spray or lotion with Deet in it will just eat right though a lacquer finish. He now has an almost new Martin D-18 with some pretty bad damage. If ya got a poly finished guitar, it'll be fine......but if ya got a Gibby, Martin, or any other lacquer finished instrument or furniture, be careful. Just an FYI, in cased ya didn't know.
