It seems like I've been getting "dry" spots in several finishes lately. Kind of like the finish got absorbed or pooled around it. Re-addding a coat doesn't seem to help much. Not sure what I'm doing wrong. I normally use pure tung/mineral spirits with a poly top coat. Here's my typical finish routine:
1- Sand to at least 220 to 320,
2 - Wipe down "wet" with MS,
3 - Rub in pure tung/MS, wipe off excess after awhile (start with 1/2 tung or less), let dry a day or more
4 - De-nub with sand paper or scotch pad, wipe down with MS
5 - Repeat 3 & 4 until it looks done, (maybe 3-5 coats without "building")
6 - After a few coats I start adding a little poly to the mix,
7 - Give a finish coat or two with thinned poly only, de-nubbing between.
Any thoughts? Can the tung get "waxy"? Should I stop with it after a few coats and then poly? I've noticed this problem a lot with the Cherry I've been using lately, but I think I had it happen on Walnut as well.
