Lexan will not last nearly as long as plexiglass.
It will craze after a few years.
The best inxpensive solution is plexiglass bolted on the outside with a good overlap, 1 1/2" all around maybe. Plexiglass can be as strong as lexan, it just has to be thicker.
I was using "Lexan" (a brand name) as shorthand for clear polycarbonate. I believe that there are UV resistant brands of polycarbonate that are about as resistant to the crazing you mention as clear acrylic (Plexiglass; another brand name). However, polycarbonate tends to be a bit more flexible than acrylic, which is one reason it resists impacts so well. That flexibility may make it difficult to keep it properly sealed. So, now that I think about it a bit more, acrylic (Plexiglass) may be a better alternative than polycarbonate (Lexan), you would just have to make it a bit thicker than polycarbonate to get the same strength.
Never forget them. Do something to prevent it from happening again.
