Not sprayed fibreglass before but mainly perspex, but I'd assume just a rub down with sandpaper to key the surface and a wipe over with sone meths to clean it up. Then a few coats of standard acrylic primer. Knock that back and then your choice of colour.
I defer to those with experience of fibreglass to correct me if I'm wrong :-)
