So i am unable to find any oil/ water based grain filler nore sand and sealer in my area, and customs seems to be against those things coming into the country, so all im left with is a bare ash body, sanded 220, 320, and i have a BIN white primed (also labled as grain filler and sealer) so my questions is:
if i apply several coats of of primer without the filler and sealer, would there be any problems/consequences to the wood with that?

I would at least put on a few coats of dewaxed Shellac as a sanding sealer before the primer...
