My car has the tiny pits pretty much all over the windshield & nothing on the bumper & hood @ 88k miles. Porsche dealer quoted $600 to replace in 2002. Went to a PCA seminar at same dealers authorized body shop & learned that they had fitment problems with some aftermarket windsheilds. Only other solution I know of is glass polishing kits which you may like since your car is such low mileage.
