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.

Thanks for your help, made me think.
