Sorry to hear the bad news but is not uncommon this time of year. Keep in mind the top is not made of traditional fiber glass, it is made from Sheet Molded Compound (SMC). Even so you might be able to use some epoxy and build it up, sand it down and paint. Bondo is brittle and the black top can get hot which will lead it expand and contract at a different rate than the top. Are there any cracks visible on either side?
That turned out nice. I did a similar thing when my HT slid off of my Jeep but my back glass broke too. I spray painted my repair work but I would like to re texture and paint the entire top one day. There is a very good write up about that on this forum.
What I did was spray adhesive around the bottom edges of my HardTop, and placed edge trim around the edges. What this did was hide all the scratches that the fall had did to it. Hell, it might even prevent and future damages, if the HT happens to fall again; it'll probably just ease the damage. For you, the best bet would be to spray paint the entire HT.
I second this, your repair and that paint look great.
I have had some minor scrapes and nicks on my top and I did a very similar process with epoxy, sanding and paint. Mine were all on the very bottom edge so they were not noticeable, but my concern was with the loose fibers continuing to unravel. A little epoxy stopped that from happening and then just touched up the edges with paint.
