I recently bought a my first black car and on sunny days you could see lots of swirl marks and light imperfections...a 3 stage polish is around £500, I have used Auto Finesse products for a while and have been more than impressed, so thought I would treat myself to the MPX Swirl Slayer kit. Obviously I was a bit nervous about using it, but I followed all the instructions and it wasn't to difficult. After using the three in one compound, I did a coat of Auto Finesse polish, and a top coat of Graphene wax... What a result all swirl marks gone, light imperfections gone, a really deep lustre and shine to the paint, it looks brand new.... don't spend crazy money on a three stage polish... simply get one of these....you won't be disappointed 👌🏼
