Plastic ain't cheap. But Lexan is UV stabilized and you can whack it with a hammer and she ain't gunna break. I once demonstrated after I fixed my let's call it drunken party house with 5 dudes kitchen window and I 360 threw a computer chair at it and it busted the frame out but the lexan piece was intact on the ground outside next to the chair. Fix er once expensive. Or several times cheap.

Lexan is different than acrylic. Lean will not break and if you look around you can find a sheet 5 by 6 all in one piece.
