Oh my god! You are a great artist and nerd my friend!
I am in my early beginning of molding and casting and I did some fails with epoxy in latexmolds until I recognized that the epoxy gets too warm for latex... Yeah and after that my molding phase (I have too many hobbies) paused. But I want to continue this some day and I will check out your fiberglass video out for sure.
Thanks for giving us an update on your DIY status and thanks for filling this blockchain with such interesting stuff man!
I'll take the 'nerd' bit as a compliment! Haha! :D
Thank you for your comments, tibfox! :)
