John..
Actually I didn't use the primer cause I found out about it after I finished. A suggestion about screws from Hunter was to remove the screws after the sealant had fully cured and fill the holes with 795. This will reduce the possibily of the plexiglass from cracking from expansion and contraction changes and water leaks. Also, mineral spirits is recommended for 795 cleanup. I am an architect and I think the proper application of sealants is one the least understood and misused building products even by so called professionals.
