scott bader developed a styrene free poly gelcoat in conjuction with advanced aerospace. don't know if it still available but apparently it worked well, but had a very strict cure cycle to ensure resin flow and bond between the two.

Worked fine for that panel.
I may try the Duratec someday. I usually cure at 100C

PPG makes a matte clear D8113 or D8115 depending on where you are. Originally developed for Lambos, not cheap but very nice and more consistent then adding flattening agent.
