Sealer for Joint Compound

Question

I just finished a butterfly made out of joint compound and PVC on 3 canvases. I’ve sanded, and now I’m ready to paint. My question that I can’t find any answers to is this. Should I seal the JC with gesso, zinsser, etc. before painting? Any advice is much appreciated. Thank you.
