I have been using epoxy primer (thanks Shine) on what few 'glass parts(front fenders) are on my car then using a 2K primer as a surfacer for final block sanding. Epoxy acts as an agent to help adhere the BC/CC to the surface and will also act as a bit of cushion against road rash. When I did the underside of the fenders I got some over spray on the topside that needed to be leveled before I epoxied - fantastic adhesion .

If this is a TP body, it might also help against gel coat stress cracks as well (from personal experience)
