I know there are some guitar pickers on this board. The following is a public service announcement from Jeff

DEET and guitars do not mix well. If you have any DEET on your clothing or your skin when you play your guitar, whatever is in DEET acts as a solvent for the nitrocellulouse finish used on higher end guitars. It will absolutely ruin the finish.

I've seen several guitars with DEET scars on the front, back, sides. Mostly from sitting around the camp fire picking or at festivals & camp grounds.

Be sure you wash your hands and arms and change clothing before you play your guitar.

DEET does keep the bugs away though.
