I put a coat of BLO on a piece of cherry and let it dry for a couple of days, then I put on some poly and it doesn't want to dry all the way. I have sanded it off, cleaned the piece with mineral spirits, and re-coated again with poly, but still no luck. I then put on some paint & varnish remover...cleaned up the piece and tried starting all over again...but without using the BLO...just went with the poly......and still no luck. It is still sticky after a couple of days. What do I do? Any help would be appreciated. Thanks.
