Hello, I have pretty good experience correcting swirls and scratches on newer cars or ones with minor issues. I recently bought a used Black Lexus with pretty bad paint. Heavy swirls, some bad scratching throughout as well as strange water-spot like places. I figure it is time to learn the microfiber or wool pad process. I am nervous about taking too much clear coat off, I don't have a gauge for measuring how much is left so I can't be sure what is there. Am I just overthinking the wool pad process? I know I would follow up with pads and lighter compounds/polish after; it is just the first time so I am a bit hesitant. What is a good compound to use with a wool pad for heavy swirls and scratches for a first timer?
