Painting 69 Dart without removing the glass

The windshield gets sandblasted and cloudy with age. A shinny new windshield will look a lot better beside new paint. I cracked my 67 windshield during removal. Once the new one was in, I was glad I cracked the 50 year old original. And that wasn't a repaint, just trim upgrade. And I also found a couple of small rust issues that weren't corrected when this car was repainted back in 1992.
As for the pollen, dust, etc., that accumulates under the reveal moldings over time.... got a pressure washer?
