Outdoor summer festivals are coming up and I'll be using a bass that is almost all tung oil-finished. Here in the Midwest US, summers are beasts for both humidity and 100+ degree heat. Based on past experience, sweat just runs down bassists' right arms on to the instruments, even if the bassist doesn't look act as though they're having a seizure. I've gone through 3 wrist sweatbands, minimum, at these gigs, even when playing at night. My questions are; - Can sweat wreak havoc on a tung oil finish??? - Is there any special care I should give the tung-oiled woods afterwards??? (BTW, I always wipe down the instrument after any use). Thanks very much for any advice!
