I want to create a watertight case made from clear acrylic (about 2 foot long by 2" wide by 4" high), but I'm after some advice on how to seal it.
Yes, I can buy acrylic glue,but it's ludicrously expensive (about £20 for a small container) and that would cost twice as much as the materials
Given the size of it, using some form of caulk or sealant wouldn't really be feasible because it would be very difficult to get it into the interior.
So can anyone recommend an alternative that would work?
