I put on the tung oil and let it sit for about 15 minutes. However the end grain sucks up the oil like crazy. So I keep Appling the tung oil with a foam brush pretty heavily during the 15 minutes. Then I wipe the doors and drawer fronts down really good. Then I let them sit for 24 hours. I rewipe them to see if I missed anything which I didn’t. However if I did it would have been a little sticky.
so after wiping the second time I took 220 Grit and very lightly went over each piece. Then I blew off and wiped. Then I reapplied the tung oil and followed the same steps.
Now this is my work bench so I only applied two coats. If this was a door or drawer front for a kitchen, Etc.. I would have done 4 coats with sanding in between.
