Hi -
On some unfinished cherry I applied three or four coats (in steps) of pure tung oil cut with turpentine and let the last sit for about 5-6 weeks. I thought I'd try satin wipe-on poly (Minwax's) so followed the can's instructions and applied three light coats over three nights. Then in searching about the wiping marks I kept ending up with I followed someone's tip in applying a light coat, let sit an hour and apply another coat for overnight. Sand with #400 and repeat. I wanted 5-7 coats anyway before applying wax.
My problem is that the wiping marks are gone but there is an uneven sheen which I seem to be stuck with. The difference is like if you apply brush-on poly, let it sit overnight then scuff it - it's usually mostly non-reflective and you can see areas you missed since they reflect more. That's what I have now. It's only noticeable with backlighting.
On the last one-two (tip from above) I wiped on circularly then a minute or two later I wiped all the poly off. I did that a couple times. It looked great and I let it sit overnight. But when I tip the piece in the light now I see the uneven sheen I described. I don't know how to fix it but if it can't be fixed, will waxing even out the sheen or just make the difference more pronounced? I don't want to get into stripping off wax if it won't so am asking first.
