I was about to spray Enduro-Var over some Minwax stain, when I read the disclaimer on GF website about not recommending use over anything not water based. Curses. Has anyone used this combination successfully? My test piece looks fine, but of course I'm worried about long-term issues. The workpiece is already stained so I can't start over. Yes I did a Search but did not turn up a similar situation. TIA
