I applied a coat of sealer because I was afraid of a few burn throughs and filler showing up in the base coat. I also thought it would be good practice prior to the base. When I applied the sealer it instantly revealed a few spots I missed on the prep work. Am I able to just sand the sealer with 220 grit, apply icing, work my way through the sanding grits, and re-shoot with sealer? Or do I need to go with 80 grit to bare metal? Will the sealer easily blend in? It's a primer sealer if that means anything. Thanks as always.
