Losing weight

How well does a lexan windshield hold up visibility wise? Can you use products like rain x on it? Glare? Bow, bend or pop out at speed? Brand preference? Thanks!
My chassis fabricator tells me that a lexan windshield is highly flammable if you ever have a fire. He advised again doing the windshield. He says all others are ok. Just an FYI/ imho. Lol
