Our machine polishes are different. They are created specifically for a random orbital machine (unlike other polishes that are created for straight drive machines) where the friction and temperature on the paint is almost non-existent. Our polishing granules are engineered to break down under light pressure, getting smaller and smaller as you use the polish. Our unique chemistry also does away with 50% of the old solvents, allowing you to clean up with water! No other polish does that. They are designed to be safe and effective at removing swirl marks and scratches from all painted surfaces. Always start with our very mild polish, Machine Polish 3, and repeat as often as you want, until the scratch is gone. If you have severe oxidation or heavy scratches, drop down to Machine 2, or our Machine 1 if need be, then finish up with Machine 3. Use ultra-fine Machine Polish 4 (sold separately) when you have nearly flawless paint and only have light swirls and toweling marks. (Like new cars that are delivered from the dealership.) It will eliminate those micro-fine toweling marks and swirls, especially in dark paints. I recommend having all four polishes on your shelf, so you can choose the perfect polish for the job. Follow up with our Paint Sealant, Carnauba Wax Stick or the fabulous Best of Show Wax® for a truly flawless finish.
