I love the tru-oil when I have the time, I have put on some of the best finishes on some of my Banjo necks and a few gun stocks,, I try to let it dry but I always seem to start rubbing it out when its a still tacky. Then it takes a lot of elbow grease to rub it out, I use brown paper bag ,wax paper, leather, 0000 steel wool. Rub it hard heat it up under what ever material I grab, I have put blasters on the plum of my hand more then once, plus I have stayed up all night before between coats to rub them out. But when finished it looks like glass but not a high gloss. More coats the better if you can hold up.
Lately on my bows if I use tru-oil I will let it tack up then rub it out with a little oil, it may be olive oil, linseed oil,lemon oil what ever is close by I also rub a cake of bees wax over the bow and the rub it hard till it heats up and rubs in, and to boot I may add some spruce or pine pitch bees wax mix and again rub the heck out of it.
Boy this is making my arms hurt just talking about it PS I also will burnish the bow with a hardwood dowel,bone.glass bottle.
Take care , Chuck
