Micro scratches or swirls I may call it. For an aggressive approach, I use a 4 step process (clay, ultimate compound, swirl remover 2.0, wax). I start by cleaning the area where the swirls are. I use "detailing clay" & water mixed with car shampoo as a lubricant other brand name products would recommend their own quick detailer as the lubricant. Until you notice the surface is smooth as silk. Repeat process if surface has rough spots. Wipe with a clean & dry microfiber cloth. Apply "ultimate compound" on the area where swirls or micro scratch. Hand polish or use variable polisher to buff area. If the swirls are still visible, use "swirl remover 2.0" apply on the area. Wipe clean & dry, buff until swirls no longer exist. Repeat process if issue exist. Finally seal it with clear coat wax, hand buff or variable polish till done.
