Kdog said:I use a liquitex gray gesso as a primer on jigs. Not sure what you mean by flaws, the primer is designed to perpare a surace to ensure adhesion of the top coat. If you have voids in the jig surface that you are trying to hide, use a filler such as drywall spackle

I tried cleaning it up as you suggested and will pour a few tomorrow to see if it is better. Also going to try Createx opaque white as a primer as I have some left.

Sometimes you can can use metal polish and felt wheel on a dremel and polish cavity and remove burrs at same time. Go slowly and be patient.
