The inside rim of my tank's top frame has long been damaged--it's not the part holding the sides together, but the little ledge that extends out into the tank. Hadn't been a big deal, but for various reasons I want to change to a lid that would sit on that inside rim.
I've tried to look for a replacement frame to no avail, so I was thinking I could trim out that damaged section and attach a wide L-shaped plastic trim strip in its place, gluing the wider part of the L to the glass just below the frame (pointing down) with the shorter part replacing the ledge. I don't need to replace the whole ledge, just about 4-5" on one side, and 8-10" on another the adjacent side.
I've been having trouble finding some of the recommended silicones around here--e.g., the Momentive RTV100 series, which has gotten crazy expensive online. Would this be what I need, anyway? Is there a more suitable product, considering the unusual use?
