'fiberglass resin' is a term that kind of bugs me.
Generally it is polyester resin and generally comes in two types, laminating and sanding. Sanding/finishing resin has a wax in it that rises to the surface and seals the resin so that it cures. Laminating resin does not have this wax and will remain somewhat tacky and will clog sandpaper.
Most 'fiberglass resin ' sold is sanding resin. This resin MUST be sanded before any secondary bonding can occur.
The lower the sandpaper grit, the more mechanical tooth there is for better mechanical bonding. Chemical bonding is not going to happen in this instance.
Fiberglass can be saturated with epoxy, or vinylester, or even freaking crazy glue, or 'Amazing goop' or brush on roof sealer, or paint, or freaking feces.
Getting a great bond to ABS plastic is not so easy.
