Update: I have been busy working on this piece. Still trying to decide how to seal it. Poly or wax???

Guess what I am doing this weekend?- Update

I sealed a red painted table with poly and the finish lasted fo years and years. The amazing thing was I couldn’t find paint in the color I wanted except in those craft bottles. Not super quality paint there, but with the poly you’d never know.
Sherrie,
The more I think about it I am leaning towards just poly coating it. I am just worried that the poly will yellow and show against the light grey paint. Decisions, decisions…
