The coveralls might be a good idea. Thanks for the suggestions. I'm hoping it is something in this particular batch of mahogany, rather than the wood itself- I've been using mahogany for many years without a problem. It is one of the most common woods used for guitars.
I used to have a few Tyvek jackets (I was a construction manager for about 20 years) and they were very lightweight. I liked them. I really hope I don't need to wear them, but they might be a good solution. Thing is, nobody knows if the problem is from contact or from breathing, and there aren't any doctors available at the dermatologist office this week. I suppose I'll continue treating it with the salve they prescribed last week, and hope somebody has a cancellation. I don't see myself giving up building, now that it is finally working out... Maybe it's time to suggest alternative woods to prospective clients..

Actually, I build guitars when I'm not talking to fish.
