Gluing/Welding Cracked Lexan/Acrylic Hatch?

What is the best way to reattach a cracked piece of lexan/acrylic? This is a chunk of my companionway sliding hatch that has been broken for years, I have used special glues that hold for a couple months but break free eventually. Wondering if there is something more permanent like a way to weld the piece back on ... ?

However you glue or melt the piece back in place, the crack will always look crummy. It sounds like UV degradation (and possibly flexing) is making the repair come apart each time you try to fix it. The best approach fix might be re-glue the broken piece in place and then cover it with a strip of teak, another plastic, or some other material that goes with the boat, glued and mechanically fastened. Five or six small countersunk machine screws pointing up, with acorn nuts on the top would do the trick. That way the broken piece won't be visible and won't come off again.

Gorilla glue... ?

I used gorilla glue on my plexi hatch cover. Used clamps and let it set overnight. Seems sound, but time will tell.
