After re-reading my post, I also wanted to add......when using Tru-oil on non-stabilized woods, the process is a long one for the best results.....you apply, let it sit for just a minute or two, then wipe is "dry" with a paper towel or lint free rag. Let it sit for at least two hours.....go over it with #0000 steel wool (lightly), then apply another coat in the same manner as the first. Depending on the specific wood, things will start to look really nice at between 8-15 coats. It's a long process, but there's nothing else that will give the look you can achieve with Tru-oil.
Tru-Oil should never be allowed to sit on wood in a heavy coat.....all that happens is what camojoe mentioned above.....it will get gummy, sticky, and be a general mess.
