Yes I did the same thing with very similar results to you. Good to see someone else in Australia getting the same results as me.
I also use the Kinetix R118, though I only use it with the H120 hardener for my room temp parts. For parts that are exposed to heat, I use Renlam K3600. It isn't an infusion specific resin, but with a 300cps viscosity it works fine. It's also very popular in motorsport, lots of professional teams using the K3600 for body panels.
The reason I use it is because it it has a very simple post-cure schedule; bake at 80 degrees for 4 hours and that's it. Tg of 92 degrees C, which is enough for most things I do. I also prefer it's clarity to the Kinetix system.
