9pcs/Set Glass Polishing Kit, Deep Scratch Remover Car Polish Pad Cerium Oxide Powder Felt Polishing Wheel Set for Windscreen and Glass(Size:9 pcs)

I have a 27 year old vehicle, with a windshield with deep scratches, medium scratches and light scratches on the windshield. I installed the round flat felt onto the tool heads velcro and attached the mandrel then chucked it into a drill. Next I thoroughly cleaned my windshield. First I washed my car down with a house and rag, then went over the windshield with paper towels and windex to remove any foreign grit that could enter the compound and cause more scratching. Then I wetted the felt on the tool head and used a small trash, I made out of a plastic water jug I cut with a knife. I poured maybe a teaspoon to half a table spoon of powder into the dish and added a little water. Just a few tablespoons to start. Youre looking for a liquid but bright red. This is the watery mix I like. Then I took a clean paper towel dipped it into my cutting mix and applied it to my windshield. This mix is watery enough to not cause friction. Its hard to control the drill and I find the tool starts skipping and becomes unmanageable if its running out of water to create a lubricant. So I keep a clean wet rag soaked with water. Then I squeeze the rag and fling it so water jumps out and onto the windshield to add a little water in a spot, then start working that water spot across the windshield. This technique keeps me lubricated and the tool from skipping so much. I work the tool back and forth all over the windshield, doing 1 half at a time. Making horizontal paths then vertical paths. The more paths you make the better results you will see. I probably did 50 passes. Eventually your cutting mix will sling off the windshield, so I add more from the mix I made and reapply. The whole process really tires your arms out, So I like to take short breaks in between passes. When I finish I clean the car up with a cleaning rag and a hose. You might need 2 rags since the cerium oxide is not easy to clean off. 1 to get the bulk off then the next as a clean rag to fully finish cleaning off residuals. The process I described also works as the finishing step when cutting plastic headlights to remove any micro scratching created during the cutting process. If you cooked into the head lights plastic at too high of speed with the higher grits, during the cutting process, its not good. You might as well go back to trying to cut that out with higher grits or accept the imperfection. This cerium oxide is only good for removing minor imperfections. Any burn-in in the cutting process seems too deep. Results: All swirl marks were removed from cutting my headlights. The large majority of micro scratches and swirling in the windshield is removed. The Deep scratches and medium scratches are still there, but it is now much easier to see out of during sun glare. I'd say its at least a 70% increase in visual quality during the sun glare hours. I think I can get better results from more than the 50 passes I did to really hone that glass with polishing. Just because these are working tools doesnt make this an easy process. Also because Im having to use a drill the ergonomics of cutting is not the best, along with the rotation speed being high. Using a drill is a "make do" tool. The cerium oxide is the right compound, the felt is the right cutting bad. The Drill is ergonomically sub optimal and I had to wrestle with it and it tired my arms out, compared to a using a tool designed specifically to tackle this job, like a rotary polisher or orbital polisher. I can make do with the drill. None of this is fun.

All the items came in a plain white box with no markings, and there were no instructions at all. I did not expect to get a complete "how to" book on using the kit, but there wasn't even a paper listing of the enclosed items. Not even mixing instructions for the polishing powder. I asked the seller and was just told to mix the powder with a little water and use the buffing wheels. I know it's not that simple. I found a YouTube and tried my best, but I pretty much wasted my time and accomplished nothing. Don't buy this unless you are already an expert and just need spare supplies.
