Wow,wildwest,revamped an old thread.Rent a big stand up floor sander,and go to town on the floor?Hard epoxy works well(as in the same stuff they put on bar tops,with stuff embedded,coins etc)unless you expect future movement(as here,so close to yellowstone.Just ripping it with a big sander can cure problems,for a while,no matter what you do for floor coating.In the perfect world,an oiled floor is awsome,but,unrealistic here in the west,where the ground constantly moves.Just my 2cents.Hope you and family are well,I am hanging in there,all ok right now.
