By diverse, they probably meant proprietary resin, typical comment from the industry..... The fact they are still resin makes it harder for real use and application, unless you do experiment with prototype.
Until then, I call horsecrap in the video. When parts that are still coated with liquid resin, this is where the object looks the best or once post treated.
Further, I'd like to know the ammount of time spent just to wipe off those half-cured resin that are a pain to deal with.
