I use Lemon oil, BLO,Tung oil,. After applying I let it sit for 12 to 24 Hrs. I seal everything i cut with a Clear Shellac spray.I even use it for oily Hardwoods.I do not use it as my finish.It takes about 15 Minutes to dry and then a very light sanding You could put any kind of finish on top of it i normally use a Lacquar finish.never had a problem When I was doing carpenter work I used to watch Painters seal everything with Shellac.
