I pulled the surgical tubing today and overall I would say a great success. It was pretty knarly break but it feels real solid and after finish one side will nit be visible at all and the other side just barely. You could see 100 squish out (barley though) and epoxy is hard enough that you cannot dent it with a fingernail but it has just a bit of flex that it should absord any future stresses.

I absolutely would recommend G flex epoxy.
