I'm finishing a black korina tele. Black grain filler, 3 coats. Clear grain filler, 3 coats completed to specs of my previous question. I don't believe I had any problems so far. I am now on coat 4 of tung oil. My question is that I have dull patches. For the most part its nice and glossy, but on the front and back are several dull spots. I am appling thin coats of tung oil, letting it dry about a week, scuffing with 0000 steel wool, wiping body with mineral spirits to remove steel wool remnits. Letting it dry 10 to 20 minutes and appling a thin coat of tung oil. Is there something I am missing. Also when finished with tung oil, about 10 coats, am I supposed to polish in some way.
Thanks
