Yes, you want to primer after sanding. There will be millions of pinholes in the fiberglass and the primer will help seal it and help you see the ones it doesn't seal. Believe me, you won't see all the pinholes unless you prime. Also, I would use a board sander to at least sand the sides after you have primed. If you don't, you will have a lot more waviness in your finish. I didn't prime and board sand the first time and I was so unhappy with the finish I bought a board sander and did it again.
