So I ran into a friend who tried to do his own glass polishing and waterspot removal. He used a glass polish called diamond magic and a 0000 white scrub pad on his drill. He did a pretty good job on the windshield and the side windows but this happened to the back window.

So I put in a order for some ceriglass and rayon pads and got to try it out today.

I got out my flex 3403 with the 2 7/8 backing pad and went to work. Taped off the trim and went at it. Used a good amount of water and pressure on the machine and presto! I was impressed.

I think he got something in his pad like dirt or maybe he didn't clean the glass good enough. At least I saved the glass and probably earned myself a case of beer or bottle of crown.

Please note that you would need to use heavy duty rotary buffer for the best result. I was quoted $1100 replacing windshield for my Porsche, but decided to give Ceriglass a try. So, I purchased $150 Dewart rotary buffer and Mcguire polishing foam pad $15.

The purpose was to eliminate glare lines caused by wiper scratches which looked horrible especially at night.

1. Installing Foam Pad: Make sure to get the one that is perfect fit for the buffer, $15 8" foam pad was definitely larger and provided perfect attachment for the buffer's rotating back pad.

2. Apply Ceriglass on the foam pad, then spray water on the pad. Spray water bottle is a necessity.

3. 1500-1800rpm buffer speed throughout the windshield, constantly spraying water when it gets dry.

$165 and an hour labor of buffing eliminated all wiper scratches, leaving clean windshield without any sort of warping or distorted vision.

Result: Got rid of all scratches, Saved $935, and I have a solid Dewart buffer for future use.:buffing:

Dewart? Or Dewalt?
 
Nice. Yes I have the 3403 that works fine. It's lightweight so I can hold it with one hand and spray water with the other to keep the machine going.
 
Have you driven at night yet? I kept seeing spots that needed refinement when the oncoming headlights lit up the windshield. Drove me nuts. Felt like is chasing my tail. Polishing glass sucks. I'm sticking to just waterspot removal.
 
I think going with the rayon pads first then going over with foam helps with the small imperfections that you are seeing. Maybe you should try that or do a couple passes with lighter pressure. I'm no an expert but before I'm finished, I do light passes and that seems to work well.

Awesome work! Glass polishing is tricky business, definitely a good alternative if replacement is the only option.

What machine did you use? I'd recommend using a GG6 with the CarPro stuff. If you use the correct technique finishing perfectly is not too difficult - similar to finishing on paint with a DA. The same principles apply - you are using abrasives to polish a surface. The same rotary "risks" that apply to paint can apply to glass as well - difficulty finishing down is one of them.

One benefit to using a DA is that it requires less skill and experience to finish down well. This also applied to glass IMHO. The GG6 has the power to remove defects from glass with the CarPro accessories.
