Need to work on windshield version 2....

Just because you have a friend with a big water jet and you CAN do something doesn't mean it's a good idea. I was worried about this. The flexing if the t-top did it. Finished off on the 100 mile drive home.

What do you think, plexiglass or a different setup with a frame?

IMO plexi is just too brittle. I suppose you could go way overboard on thickness, and get added toughness, but it's still not going to take repeated flexing very well.

Polycarb would hold up a lot better, but needs care (though I've been running mine for about 3 years without any noticeable degradation. I suspect sun will eventually do it in, well before scratching.)

I don't even like when guys bring glass bottles on board, much less having a glass windscreen.

polycarbonate is Lexan and acrylic is Plexiglass?

Acrylic is cheaper and polycarbonate is stronger. Something like that?

Polycarbonate scratches easier.

So scratch resistant coated polycarbonate is the way to go?

Polycarb also tends to break down in extended UV exposure (at least for bulletproof windshields; they derate external windows based on time since install.) Don't know if that makes a difference or not in this application.

If, as Nugent posted, there is a plexiglass that is close to as tough as polycarb, I'd look into that.
