Just to throw in my 2 cents, I use AlumaLite and am happy with the results. I’d probably do this one in a couple of pours, but I think it’d work out. It’s not a deep pour epoxy, although they do make one. But a couple pours isn’t a big deal to me. 

Ryan/// ~sigh~ I blew up another bowl. Moke told me "I made the inside bigger than the outside".
