I have to point out that I *also* learned years ago about clouding canopies with Isopropyl. The wipes I referred to are used for the plane - I don't do the canopy with them. I have a plastic cleaner/polish from the aviation industry that I use for the canopy only. It may seem like a pain, but I like the canopy to remain as good looking as it can.

Bug guts make cowls and canopies a special challenge in our location.
