As stated in other posts Flex o glass is crystal clear plastic. I actually got mine off of Amazon through one of their cooperating merchants.
As an update the two sides I did are still on the tractor and haven't moved a bit. No reason you couldn't put it all the way around. With the way I have it mounted at this point there is air coming in at the bottom.
I'm planning on going all the way around but am wrestling with the "door" situation. The magnets I used are really strong and I need to pry them off to remove them. I have to either get weaker magnets or work out a system which allows them to be further from the metal and thus not holding as strongly (but strongly enough). I'm considering embedding them into a piece of wood and attaching the flex o glass to that.
My other "problem" is what to do around the back of the tractor when the backhoe is attached as the "cab" would be in the way. Not a problem in the winter when the cab will be most useful.
I figure what I will ultimately do is mount the flex o glass into wooden frames with the magnets attached. The frames don't have to be very strong as the magnets hold the whole thing. Then I can just take the frame off using the wood to pull off the magnet and have the right size panel ready to go.
