Review on 🔮 GPA14004 High-Grade Polishing Compound Solution by Shawn Tolbert

Works as advertised. There were a few scratches on my new Acura's windshield that looked like someone sanded them off with 400 grit. (see before photo). Some were deep enough to feel with a fingernail (not all deep ones came out). The dealer didn't fix the problem and said it wasn't their fault. I purchased this product and glass spacers from Griot's Garage for my Porter 7424.1 cable. Wash the window thoroughly 2. Tape off the wooden strips and cover the paint with plastic garbage bags3. Place about 1 teaspoon in the center of the pad and spray with water to wet the pad4. Started with setting (1) on the porter cable, which sits at around 2400 rpm. There was noticeable improvement, but I had so many scratches that I repeated this 4 times before moving on to the next step.5. I then turned on setting (3) on the polisher and worked 10 more times with decent pressure. Every 4 passes I wiped the glass down with water and a paper towel. Then I added another teaspoon to the pillow. Always add water so it doesn't dry out from friction.6. Once the main areas looked good, I made 3 full passes across the windshield. This got rid of the old RainX and that annoying frame that the wiper blades create in the glass.7. Tape and plastic removed. Washed the whole car.8. Sealed the windshield AquaPel.9. I didn't shoot everything because I would have to grind the glass down pretty deep. So I'm happy with the result and it looks great. (see after the photo).
