Thanks Don and GM!
GM, I never tried silicone, but when I started researching how to create water it was clear (no pun intended) that it was not the way to go. I ran across a few build that used the acrylic gel, tries it myself and was sold.
Information on how to make water on the internet for scale ships is nigh impossible to find.
I will be doing a YouTube video how to do it sometime soon.
