Thanks all for all the input on what I'm sure is a well thrashed subject!!
Olive oil eh? Cold pressed? Extra virgin? Actually, I think I'll try OO on something.
The videos were very informative - Thanks!
I went ahead and used neatsfoot on a holster I just made (WWII 1911 style for web belt - no tooling), and yes, it turned dark. That's OK.
Thanks again!
BTW - this is a great forum! LOTS of activity - so much to learn!
