You do not need to use a primer with our products, however we know that some customers prefer to routinely prime models before painting. We sell Humbrol Primer.
You should use only acrylic paints. Enamel paint can have a very undesirable effect, so we would recommend avoiding enamels completely.
Resin can be cut using a Dremmel or fine saw and sanded using a fine sandpaper or nail file.
If you're gluing resin parts together you should use a superglue or epoxy-based glue. Regular plastic glues will not glue resin. We also sell superglue.
