Sides down to fiberglass - do you paint?

I recently purchased a 1975 Flying scott that is in wonderful shape.  The sides have had the old paint sripped down to the fiberglass.  While it looks nice, Does this need to be preped and sanded to prevent sun damage, or can it be left?

I presume that the boat was painted at some point which you removed. If the hull is in good condition, buff and wax it with a good compound and wax made for fiberglass. If left alone, over time it will oxidize. Hope this helps.
