I have been using T&T on all of my pieces for about 8 months. I mostly use their Danish oil, but have used their varnish oil on several pieces. I noticed when the weather cooled off last fall that pieces left in the shop were taking much longer to cure. I have been bringing them inside the house between coats to help with that. Even inside, the varnish oil takes a long time to fully cure. I have found that it works best if applied very, very thinly. Sanding to a high grit seems to help keep too much oil from absorbing at once. With the Danish oil, any figure looks flat after the first coat. After curing 8 or more hours inside (24 hours for varnish oil), I burnish the surface with 0000 steel wool, then apply the second coat. By the third coat, the figure will pop and thats usually where I stop. Honestly, I don't see much difference in the finished surface with Danish and the varnish oils, so I tend to just use the Danish since its quicker. If I want a shine, it buffs well.
