Time for a new top. Asking a few questions.

[Perfectlap]

My plastic window was spotless until it similarly succumbed to below freezing incident. I was hesistant to go with the M1 Tank field of vision with a glass unit so I had the plastic window replaced for $400. Not the smartest move looking back as the money would have been better spent goiing towards the replacement top but my canvas was in excellent shape.

But to all the plastic window owners, don't clear ice/or snow from it with any force. And certainly don't use an ice-scraper. I managed a hairline crack simply sliding a piece of ice off the plastic to quickly. At freezing temps it can break easily. Best thing is to pour hot water over it. And if you want to lower the top below 60 degrees warm up the cabin after driving for about 10 minutes first. Don't drive off on a cold day with the top down from a cold start. You'll wreck the plastic. Greater visibility requires a bit more care with these tops.
