I just called a plastic company to price half inch Lexan skylight
replacement. They said that, although Lexan is stronger, acrylic will last
longer in the sunlight and is more scratch resistant. They had no idea what
"longer" means.

If Lexan lasted 10 years instead of 20 I'd be happy. If it was 5 instead of
10, I wouldn't.

Anyone here have an idea what the real numbers might be for clear skylights
on a sailboat in the Northeast? Any other pros or cons for one plastic vs
the other?
