Deft used to be brushing lacquer, God only knows what it is these days with all the VOC restrictions. Careful with mixing WB coatings. Stir only or you can create bubbles which don't go away for a LONG time. BLO is an oxidizing type finish, meaning that oxygen in the air causes it to cure, just very slowly. By not thinning it you slowed it down even more and then putting a WB coating over it made it so it can no longer cure. Target Coatings makes a WB shellac that is supposed to be pretty good. I would suggest using that instead of the BLO when using water based products. I think it is better to stay in the same chemical family if at all possible.
