After the epoxy fillets had dried, some high spots were taken down with some 220 grit wrapped around a dowel. As epoxy dries, it self-levels. The surface should be pretty smooth already, requiring little sanding.
Many builders will add Micro-Balloons to the epoxy mix to make it easier to sand.
Others say it diminishes the strength of the epoxy bond.
The entire model was shot with gray primer.
I tend to shoot only one coat of primer and sand almost to surface.
Other people will shoot several light coats, sanding between coats.
Whatever works best for you is right. I just don't enjoy all that sanding!
After all the fillets and prep, here's the back end ready for the first white coats.
