Quote: I use Rain-X on my Aeroflow windscreen and think it stinks - actually, it doesn't work at all even though they recommend it be used on their screens. Do you think that Raincoat would work better on that type of acrylic than the Rain-X does(n't)?
Well the makers of Rain-X are quite clear it is only for glass. And if you call their helpdesk, they will tell you not to use it on acrylic plastics found on some windshields. The alcohol can leech out the plasticizers. You might end up with a very hazy shield over time.
Rain-X did not seem to do much on my polycarbonate shields. Virtually all faceshields are polycarbonate.
Raincoat is designed for plastics acrylic, polycarbonate (Lexan) etc.
