I'm working on a slab of maple and have applied two coats of Minwax Tung Oil Finish. There are a few spots of small tearout I see now that I'd like to go back and resand. Is that possible? or am I just going to muck things up. I'd assume in the best case scenario I'd resand and then reapply tung oil in those spots. I'm planning on finishing with a few coats of poly after the Tung oil.
