Sadly, replacement windshields have gone down the too familiar path of lower quality standards that everything else in our society seems to be taking. I'd stick with PPG, if possible, but there are other factors that might affect pitting.

How bad is the acid rain in your part of the world? I'm no wacko on the environment, but can assure you that acid rain is taking a terrible toll on auto finishes in most parts of the country. Ever notice all the plastic tape on new cars as they come off a transport at a dealer's lot? It isn't put on the cars for decorative purposes; it is to protect the cars from acid rain damage during shipping.

Sandblasting could be the problem, I suppose, if one lives in the southwest. I'd give more credence to other environmental factors, though.
