Help!!! New oak material, Sanded, cleaned off dust with air compressor and vac. Applied Watco Statin (med. walnut) dryed for 24 hours. I applied Deft Lacquer finish (critter gun) and got terrible fisheye in the finish. I have done this before with no problem. I’m open for suggestions. Don’t want this to happen again. I enjoy Knots. You wood workers out there have great ideas and helpful notes. A side note!! My workshop is in an old barn. Shop size is 48×48 and heated. Nothing fancy but does a lot of work, I keep busy , customers like my work, and its great therapy.

Using a lacquer based finish over an oil based finish is not a good idea. The solvents are not compatable. You can sometimes get away with it if the oil based coat is fully cured (year or so) but in most cases, the lacquer solvents dissolve the oil based solvents.
At this point, your best bet is to strip everything off and start over. If you spray a coat of 1# cut of shellac between the two finishes, you can overcoat with lacquer.
Howie, i spray lacquer over oil stains all the time without any problem, and no shellac between. And i use Deft as a component of my lacquer mixture. (see FG's thread on semigloss finishes)
I suspect there was some contamination of the brush, the can, surface the piece was laid on...whatever...with silicone, before the spraying.
The watco tends to cure over lots of time. I don't know about 1 year but I use the polyurethane over the watco but let it dry a week. The pores of the oak tend to hold the watco then weep out . Paper towels to wipe it down as it dries and a soft cloth after it seems like it is totally dry. PS did you shake up the can? possibly driers settle in the can and need to be mixed into the stain.
A 24-hour cure time isn't anywhere near long enough for Watco. It needs to dry until it no longer has that Watco aroma. Personally, I don't know about applying lacquer over it, but whatever you use, let it dry several days, then do the sniff test.
PS: with regard to the "weeping from the pores" problem, I've recently finished some red oak with Watco, and following suggestions from this forum went to the wet-sand program and had much, much less of a problem with the weeping. Although it was suggested to use 320 paper, I liked the appearance with 220 better; put just enough Watco on to reduce the drag of the paper but not so much that there was no friction. Sanded with medium pressure for awhile, then wiped of the excess. Kept an eye out for the small weepies that appeared and wiped them off. Re-applied the next day,same routine. Turned out great.
