What to Use to attach Plexi to Plastic????

[GMGQ]

Silicone actually dries pretty sturdy. Just squeeze a good bead along the bottom, and press it down, and squeeze some more around to fill in the edges, and let it cure overnight.

I used it to put lucite baffles in my sump, holds rock hard. It was actually a PITA to remove when I wanted to change the layout of my sump!
