How to do Topical Glass Polishing with Diamondite Glass Polish by Mike Phillips
A few months ago, in preparation for my 5 detailing classes at the 2021 Southern Detailer's Conference, I went to Snake Road Salvage Yard to get a windshield to use for a teaching topical glass polishing. Initially I was looking for any old windshield already out of a car. As good luck would have it, my friend and owner Phil offered this 1950s era Ford F100 Pickup windshield they had removed from a truck for a customer who never claimed it. As such, after removing it - they stored it along side the building in a patch of grass where a sprinkler sprayed it regularly with water for about 4 years.
Upon seeing it - I knew this would make for a DRAMATIC before and after teaching class showing others the need for and benefit to machine polishing glass to remove TOPICAL staining.
Here's the windshield...
Before the first day of classes started I did some testing to make sure of the results before doing this LIVE in front of paying customers. (normal protocol)
Because the curved sides would be awkward to "demonstrate" on live in a short amount of time, (I was also teaching SUB-SURFACE glass polishing showing how to remove scratches and wiper-marks IN the glass), I machine polished the outside portions of the windshield.
Here's a couple of pictures I took, (my point of view in a class), right before the demonstration.
Fast forward to last night when Yancy and I did a LIVE Detailing Class on how to do Topical Glass Polishing.
Here you can see the sections I machine polished on the outside of the glass and the middle section I did LIVE in the class.
For the LIVE class on this topic, I'll include the video below. It's in-depth and fully explains why to do topical machine glass polishing and then shows how to do topical machine polishing. For the video I machine polished the right hand side as you look at the picture below.
AFTER the LIVE Class
After the live class I finished the job and took these pictures...
Me doing me...
Spraying on some of the new Diamondite Glass Cleaner Aerosol to help remove all the icky residue...
Wiping.... that's a "The Rag Company" FTW or For the Windows orange microfiber towel - I really like these for working on car paint.
Wiping....
And - BOOM!
Glass goes clear!
Works great for TOPICAL glass polishing.
And the film that was on the glass? It's now on the pad. I'll wash this pad in the washing machine with some other glass polishing pads I have but from here forward, this is a dedicated glass polishing pad. Never to be used on car paint.
Big Picture
There are two types of glass polishing - Topical Glass Polishing and Sub-Surface Glass Polishing.
Topical Glass Polishing
Topical glass polishing is where you hand or machine polish glass to remove various films like road film or water spots or drizzle stains OFF the surface of the glass. Topical glass polishing does not and will not remove scratches IN the glass.
Sub-Surface Glass Polishing
Sub-surface Glass polishing is where you use a specialized glass polish that uses Cerium Oxide as the abrasive technology and usually a rayon buffing pad to slowly and methodically abraded the glass to level it and thus remove swirls, scratches and wiper-marks that are IN the glass or below the surface of the glass.
HUGE DIFFERENCE between these two types of glass polishing and I'm pointing this out in this article and I point it out in the video below BECAUSE there is a LOT of confusion over this topic. Hopefully after reading this article and watching the below two videos everyone will be on the same page when we talk about glass polishing.
