I have stopped leaks on mine by running a bead of non-permanent silicone btwn the header bar and the hard top and also around the screws that attach the top to the header bar. Those cupped indentations on the top for the headerbar screws catch water and that is the main intrusion spot. Also closed cell foam tape btwn the different sections of the top.
The silicone I have used is designed to temporarily seal household windows for the winter.
I have been putting the fiberglass hardtop on for winters since about 2002 (but skipped a couple winters thru the years and will probably skip this winter as well - it is a bit time consuming if you do it solo)
I like the look of your top painted
