65d will warp in heat. Use 300. It’s plenty durable for its intended use, which hopefully isn’t dropping on the ground >_>
For mass production casting from a silicone mold, SmoothCast 300 roto cast is the industry standard.
(Flex is not a huge difference from 300’s 70D by itself. )
Regarding the Deployment FAQ:
Suggest changing from "go to our Application Forms page, and click Request Deployment." to "go to our Requests page, and click Request Deployment."
Maybe I'm completely blind, but where is the application form at? I can't seem to be able to find it.
Edit: Nevermind I'm dumb and found it. I was looking for "Forms" and it's under "Requests". Might want to consider changing the wording in the first post to make it a little clearer?
