35 years of paint and body experience and I have Malibu Teal which is black with Teal flake, and black gel coat on the bottom. I used “3m finesse-it” for years, and it was good stuff in its day. But technology has way surpassed it. I now use Meguirs 105 Ultra Cut compound for heavy scratches and finish with Meguirs 205 Ultra Polish to finish it off. Then put a good protector on top. Absolutely No Swirls whatsoever. And as already stated… A Polisher that will run as slow as 1500 RPMs and a dark grey 3m waffle pad for finishing, and white waffle for heavier cutting which it dont sound like you need. My 93 looks brand new!!
