Need help deciding on silicon for 440 gallon build

[wakesurfdan]

I'm starting my assembly of my 120"x33"x29" next weekend and need help or recommendation on silicon! The glass is 1/2" and will be spaced with 1/16 spacers. My build thread is on do it yourself titled 400 gallon glass build!

Thanks everyone Dan

I use GE RTV108 on everything but think it is called Momentive. I usually order it from Mcmaster Carr as Grainger no longer carries it in my area.
