Oil based wiping cut of Poly over nitrocellulos lacquer

[Admiral]

I'm finally getting around to trying to fix a table top that had water damage (my bride put some jugs of water on top to prep before a hurricane, and they leaked).

Question is, has anyone put a wiping cut (50-50 oilbased poly and MS) over a nitro finish?  I'm thinking of evening out the flaked portions of the  nitro with acetone, and then hiting it with 400 grit (or OOOO steel wool) to rough it up, then wiping on the cut poly.  Any advice is welcome.

I've never done what you propose, but I'd think about spraying a coat of dewaxed shellac over the lacquer before wiping on the poly mix.

Thanks, I’ve seen that mentioned in the guitar forums, they deal with nitro a lot.
