I have a couple of 1 oz bottles of 100% DEET, which I'm not going to
use. But I thought I could just dilute it to 30% and have 6 or so oz to
use in a spray bottle.

I looked up the MSDS for the 30% variety & found the solvent to be
ethanol. I went on & looked up the MSDS for ethanol & found that it is a
skin irritant! WTF - a solvent for repellent that is a skin irritant!?
Well, that's crazy, but it's never bothered me, so what the hell.

Now, as far as the ethanol to use: is it even available? I'm assuming
that denatured is out because of the methanol in it. How about
isopropyl? Is it such a different animal that it wouldn't work?

Sounds even worse than H2O:
"Skin Contact:
May cause irritation with redness and pain.
May be absorbed through the skin with possible systemic effects."
