I purchased a new unfinished aftermarket swamp ash Telecaster body. The manufacturer grain filled it with Bartley's Grain Filler (oil based) without any washcoat (the body has only had the grain filler applied). It looks like there are some spots that need touched up. Would it be ok to use Z-poxy to finish the job (any adhesion problems since oil based filler has been used)? I am not concerned with the different colors because it will be a solid color guitar.
I know nothing about Bartley's grain filler but I would do a test on scrap to insure the Zpoxy will adhere, plus i suspect there will be a noticeable variant in the touched up places and those that will have the Oil based fill with a shim coat of Zpoxy over them. you might consider sanding back to bare wood everywhere and do a fresh fill with Zpoxy.

Also, if I finish it with Nitro, would it be better to use some kind of poly sealer to prevent shrinkage or just seal it with vinyl sealer.
If you end yp with a Zpoxy fill then the vinyl sealer will be fine.
