The 140 is about 90% better than the RS was. That was terrible for coating the back. In this, even after several weeks at this time of the year it's still not too bad.
There's enough vision through the grime combined with slightly adjusted door mirrors for me to be able to see all I need out back.
Which is exactly why this is as far as I got last weekend...

This is news to me. I thought that the nature of a ceramic coating was that it provided an almost impenetrable protective layer?
