Scott recommended this to me a couple of years ago and when I tried it I was really amazed how well this did work!
I did the windshield on my truck, which looked clean to me, and I was very surprised at the clarity once I was finished.
I used DP Glass Restorer
on a White 5 1/2" flat foam pad with my Porter Cable 7424 dual action polisher on speed 4.
It took be only 10 minutes or so to give the glass a new fresh look.
Once I was through I washed it with Meguiar's Glass Cleaner
, thoroughly dried it then applied a complete coat of Aquapel.
This product is very impressive, give it a try, I'm sure you'll be impressed...
