Mike, how much time did you spend on each section?
It's been a while since I remove the pinholes out of the windshield on the Mercedes-Benz, but if my memory is working correctly I would say the entire windshield took me about 2 hours, so around an hour a side and if you read what I wrote in Post #7

So that would mean I spent about 30 minutes on each quadrant. Could have been longer, would not have taken less time. Glass is hard.

Yes but don't get the glass to hot as there's a film of plastic sandwiched between two sheets of glass that makes glass "safety glass" so it won't shatter. I'm not sure it's a good idea to get this plastic film real hot.

The Glass Restorer is for removing "topical defects" like water spots "ON" the glass, it won't work to remove defects "IN" the glass because it does not contain Cerium Oxide. Cerium Oxide is the key ingredient for glass polishes designed to remove defects OUT OF THE GLASS.

The first picture I posted in this article was taken from the inside of the car. This shot is from me sitting in the car shooting at the inside of the windshield.

Here's the thing... once you remove the defects... there's nothing to take a picture of... (except clear glass and that's hard to focus on too)

Re: How to remove tiny pinhole pits in glass windows using a rotary buffer
hate to bump an old thread but i need to do this badly on my car and the 20% off memorial day sale ends in 1h 45mins. the cream mike used is out of stock. so what product should i get?
will CarPro Ceriglass Glass Polish work the same? get the deep little specs out like mikes before pic?
the cutting pads are out of stock and the polishing pad has 2 bad reviews for velcro not sticking
will Griots Garage 6 Inch Glass Polishing Pads cut any, or do i need a cutting pad? or will they work well enough?

Are you trying to remove scratches or just surfaces defects like water spots?
I never tried to remove scratches so I can't help there but for water spots, any polish should work. I used Mothers Chrome Polish with a white LC pad and a HF DA and it came out perfect.
Free bump.

Re: How to remove tiny pinhole pits in glass windows using a rotary buffer
cruzer23, I used the CarPro Ceriglass product and it works as advertised. I used my Flex 3401 as I do not have a rotary and the GG Microfiber pad. It was a LOT of work. In fact, I gave up after about a 50% improvement. I found it helpful to have an assistant on hand to constantly spray the work area with water to keep the product working. After I bulk up my arms a bit in the gym, I may go after the last 40-50%. And yes, it makes a mess, so cover up the car with towels, sheets or you will have a lot of cleanup to do.

Sorry, I just realized I responded to a year old comment. Oh, well.

CarPro Ceriglass has been good to me for moderate to heavy stains on glass (only had a few small light scratches that are now gone). My go to when needed for light to moderate is the McKee's 37 High Performance Glass Restorer and by far that is my favorite glass polish.
i bought the Wolfgang Perfekt Vision Glass Polish before it was buy one get one free and in my experience, the mcKee is a better product . Easier to work with and gets out the contaminations easier and quicker even water spots on the paint.
Re: How to remove tiny pinhole pits in glass windows using a rotary buffer
Mike, any idea what to use to remove Ceriglass from inside the pitting of the windshield?
I have some bad wiper trails on my car and went to polish them out today. I have polished several windshields in the past even though we do not regularly polish glass at the detail shop I work at (99% of the work is paint related).
My car is relatively high mileage (over 100k miles) and has a decent amount of pitting on the entire windshield.
After doing one test section (luckily on a lower, less visible part of the glass), the wiper trail was reduced by maybe 30-40% which I was happy with, but I noticed the Carpro Ceriglass basically filled in all the small pits in the glass and now they appear as white dots.
I tried removing them and got some of it off but not completely. Looking for some ideas.
Here is what I tried:
1. 70% IPA 50/50 sprayed onto the glass and agitated with a stiff boar's hair brush and wiped off with MF towel...this did little to nothing.
2. 3M General Adhesive Remover sprayed onto the glass and agitated with a stiff boars hair brush and wiped off with MF towel...this also did little to nothing.
3. LC purple wool buffing pad and 3M adhesive remover with a Flex 3401 (I thought maybe the buffing pad would reach into the pits and clean them up with enough pressure). Nothing happened.
4. 2000psi pressure washer at a close distance...this, I want to say, cleaned up the compound some to where it's not an eye sore anymore and virtually invisible from inside the cabin, but still visible from the outside in the right light/angle.
I will not continue polishing the rest of the windshield before I figure out how to get around getting product stuck inside the pits.
This is pretty much the only thing I can find online suggesting to use a nylon bristle brush and scrubbing the area with liquid dish soap to remove the compound from inside the pits:

I will try this and hopefully it does the trick.
Any other ideas?
Thank you Mike.
Re: How to remove tiny pinhole pits in glass windows using a rotary buffer
Our '05 Pacifica has bad pitting...tried just normal DA polisher and normal compound, but no joy. How much more powerful is a rotary like Mike used compared to an ordinary household drill? Is a rotary unit a specialized tool that I'd need to tackle a job like micro-pitting on a windshield?

It will still take an extremely long time no matter what buffer you use. If the pitting is pretty deep, be realistic in your expectations. If you're expecting perfect and you have an older car with tons of highway driving damage, you're in for a big disappointment.
