Default Nitrocellulose lacquer over an oil?

Not having spray gear, the only lacquer I use is Deft. The instructions say it can be used over *thoroughly* dried oil and I have done so, NP.

Ahhhh.... the much maligned Deft. I started as a full time
woodoworker in '75, and it has been around a lot longer than that. I
still use it today on occasion if I am called on to finish small
projects (cabinets) or interior doors.

That has to be the most forgiving, applicator friendly finish around
that will give great results. I have switched to the Old Master's
brand of lacquer now due to its higher solid content, but wouldn't
hesistate to use a can of Deft
when needed.

I built a desk a few years ago that I pretreated to highlight the
grain with a homebrew of shellac, real turps, tung oil and BLO. I got
that recipe from some furniture maker....
I finished the desk with about three coats of Deft, ONLY sanding out
nibs. Remember with lacquer, scuff coats are not needed and they can
cause more problems if you scratch your surface.

When I spray Deft (or any other lacquer) I usually spray, wait about
forty five minutes, then spray again. Then I wait about an hour and a
half, then spray again. Then about 2 hours, then spray again. I
dont' usually spray more than 3 - 4 coats in a day (unless I am using
my purpose made high dollar stuff) as you can build too fast and get
some blushing. Beware that if you put 3 - 4 coats on the piece, you
should leave it for a few days to cure out before a installing the
piece or a lot of handling takes place.

When I brush or pad, I apply a coat, then wait two hours, then apply
another. I wait about three or four before applying the third coat.
If it feels soft or even the slightest bit plastic I wait longer. For
sure with pad or brush, no more than three coats in a day.

Anyway, do what dadiOH said, let your oil pretreat/enhancer dry
completely (one week to be sure, less if you are in a hurry) then the
Deft will adhere fine.
