Well, if it was a guy off the street, I can certainly understand him being uninformed about what oil based ointments can do to a snakes scales. Also explains why he told you a scar like that would be good as new after a few sheds. Whew! Glad you cleared that up...I was worried that a Vet could be that clueless about general snake care.
I don't do snake med VTC's...I'm just a guy off the street.
