Took 20 years off my windshield!!

Awesome! This has been on my list of things to do, as there are wiper blade scratches on my boxster windshield, and I wanted to restore like-new clarity.

As an experiment, I tried polishing a section of a car windshield a Menzerna automotive paint polishing compound that is supposed to work on "hard" clear coat (thinking that might have some chance of working on the super-hard glass windshield). It seemed to make some progress, but it was far too slow to want to do the whole windshield with it.

So you just bought this powder and mixed it into a slurry/paste with water, and only took 20 minutes to do the whole windshield? Sounds pretty easy!

Did you end up with any optical distortion through the polished surfaces afterwards? (This can be a worry when polishing an optical surface if material is not removed evenly enough.)

@jakeru depending how badly your windshield is marred, it may take quite a bit longer than 20 minutes.....I had some heavy wiper blade marks on mine....took me closer to 1 1/2 hours as I worked in small sections...about 2 ft square....buff...clean the section...evaluate...repeat as needed while viewing from all angles to ensure you got all the marks.

no distortion afterwards.

Agree with Dan....mine was far quicker but it could take you longer. No distortion just beautiful clarity.
