All thumbs are out the window when you get into more technical glassing.
You could go down the rabbit-hole real quick just browsing around at the Composites One website.

Well, I had a couple university classes in composites 20 years ago, and can't remember much other than the math for stress analysis for multi layer uni axial layups of carbon in epoxy was hard if you do it by hand.
With respect to resins? We built a lot of VE structures at school. The lead fabricator (school employee) had developed an epoxy sensitivity.
But I don't own a boatyard. All I can do is interpret data sheets (I have done most of the ASTM tests at univeristy years ago). But that isn't the same as building boats for 20 years.
But my first scratch built monocoque fiberglass (R/C) car was at age 14
.
Then a 15 year hiatus or so.
But I am a weekend warrior, mostly. I only ever got paid to work on aluminum "Navy" boats, and then only briefly.
So like any advice on the interwebs- you get what you pay for.
