Removing Wiper Scratches out of the Windshield on a 1964 Corvette Class with Mike Phillips

Before & After Pictures
Below are the before and after pictures from this glass polishing class here at Dr. Beasley's in Stuart, Florida. This is a FREE/BONUS class that takes place the day BEFORE the actual class. There's simply not enough time to ADD this topic to the full schedule of topics we already cover in our classes. I hold these the day before the for anyone that wants to attend and because MOST of the people that historically taking a class I teach are flying here from other states, or other countries.

For example, in this class, Nelson flew here from Bogota, Columbia and Nicolas flew here from Buenos Airs Argentina. I get the car, I get her prepped, if anyone taking the actual class would like to learn how to take scratches out of glass, then it's up to them to figure out their travel schedule and get here.


Here's the victim - an all original 1964 Covette

BEFORE PICTURES
In the picture below, you can EASILY see the wiper scratches as they form an ARC pattern that mimic the way the wiper blades move over the glass. As I type, this car, and thus this original glass windshield are 62 years old. At some point over the last 62 years, the wipers either became worn-out enough to cause scratching, or some kind of airborne debris, like beach sand, (common to coastal towns and the desert), is blown onto the car. This contamination will land on the top portion of the rubber blade and the next time the wipers are turned on, it rubs any dirt or sand over the glass and overtime, you end up with some pretty bad wiper scratches in the glass of the windshield.

Not only are their wiper scratches in an arc pattern, there's also random scratches throughout the windshield.

Passenger Side
The passenger side actually had some scratches that are deep enough, if you drag your fingernail over the scratch, your fingernail will drop INTO the scratch. If this happens, the scratch is deep enough that the only time-efficient method to remove the scratch 100% is to machine sand the entire windshield and then buff out your sanding scratches. I do NOT recommend this for 99.9% of Earth's population. Too risky.

A better plan
When you have deeper scratches in a classic car windshield or even side or back glass, a safer approach is to lower your expectations, decide you'll LIVE with the deeper scratches and then do you best work to machine polish the glass. A thorough machine polishing using a dedicated glass polish with a rayon pad on a rotary polisher will easily remove the millions of shallow scratches and will clear-up the deeper scratches that polishing along will not remove.

How to Prep a Car for Glass Polishing
Here's what I do, you can borrow this approach if you like or skip it and pay the price later.

Step 1: Use painter's tape and tape around the trim on the windshield.

Step 2: Cover the car in a plastic car cover or drop cloth.

Step 3: Cut out the plastic around the windshield and then tape the plastic to the tape frame you've already applied to the outside of the windshield. It's faster and easier to tape the plastic to tape already applied to the window frame than it is to try to tape the edge of the plastic to the actual window frame.

It's Go TIME!

Up first are Eugene and Doug. Eugene is using the RUPES rotary polisher while Gene is using the FLEX rotary polisher.

See the Nr. 00002 on the sticker?
This is the Number #2 FLEX PE-150 corded rotary polisher given to me by Bob Eichelberg, formerly with FLEX, retired now. Thanks Bob!

What Kind of Polish?
In order to remove scratches out of glass you need a dedicated glass polish. A dedicated glass polish is a polish specifically formulated to abrade or chemically melt glass. There are two types of glass polishes that I've used that actually work. There are cerium oxide glass polishes and there's Dr. Beasley's GL Glass Polish that does NOT use cerium oxide but instead uses a unique ultra-hard nanoparticle abrasive technology.

From the Dr. Beasley's website

NSP GL Glass Polish
PATENTED NANOPARTICLE ABRASIVES FOR A FASTER, MORE EFFICIENT CUT
After rigorously testing multiple abrasive types, Jim sourced a unique, ultra-hard nanoparticle abrasive with diverse applications. This patented technology is used by the Air Force to polish F-35 fighter jet canopies for crystal clear in-flight visibility. Through careful engineering, Jim adapted the technology for automotive glass. Testing the technologies side-by-side, he found the patented nanoparticle abrasive to be superior to cerium oxide in speed, efficiency and clarity.

Urban Legends
I've been doing sub-surface and topical glass polishing for DECADES. Anytime I share any glass polishing project on any social media platforms, like Facebook, Instagram and YouTube, there's always an expert that states

Any compound will work

Of course, this is NOT true and of course, the expert NEVER backs up what they state by showing their process in any way, shape or form. It's always the same thing, lots of talk, no walk.



Lead by example
I never aske my class to do anything I'm not willing to do myself. Sub-surface glass polishing requires some muscle, tenacity and time. I'm willing to take on these types of projects and after taking this class, I'm confident the students taking our classes will know what to do and how to do and just as important, they'll know how much time is involved as well as physical work.

Here's Eugene, still working on the passenger side, while Nelson, who travelled all the way from Bogota, Columbia to take this class has now joined us and is working on the driver's side.

Switch Sides
You can see Nelson and Eugene have switched sides. Running a rotary polisher on an glass windshield at an ANGLE - stresses your deltoid muscles as you use your arm to press the rotary against the glass. A trick I use and teach is to switch sides and use the other arm for a while and if you feel your muscles getting tired, switch again. When I work by myself, I do this same thing with two workstations set up on each side. This way I can simply move from side-to-side without having to drag my tools, pads and towels from side to side.

Juan has joined us next. Juan came all the way from Kentucky to take this class.

Time to de-tape and check out the results
It's now late in the afternoon and time to wrap-up the glass polishing class.

My comments
First, let's put this project in context. I think it's accurate to say, this is the first time for all of these people to do Sub-Surface Glass Polishing. Polishing scratches out of glass is nothing like polishing scratches out of car paint. Glass is super hard, and it doesn't abrade or polish like car paint. Due to the hardness of the glass, polishing a windshield out in the condition this windshield was in before we started will take both time and perspirations. But with enough time, you can remove the bulk of the swirls and scratches. The only defects left behind are the deeper scratches and this should be expected.

My opinion is, knowing this was each person's first time doing this type of work, they did GREAT! And more important, when they leave this class, they'll possess a brand-new skill that can help them moving forward anytime they are asked if they can remove scratches out of the glass on classic cars, muscle cars and streetrods.


Thanks everyone!


Mike
