...and I stopped what I was doing to come write this review. I recently acquired a dream car for me, a 2003 midnight blue 911 turbo. The car was perfect except the previous owner never detailed it and the paint was awful, swirls and RIDS everywhere. It looked truly awful. Being a lifelong Menzerna user (SIP, IP, Nano Polish) I wanted to stick with them, and read that FG400 was the latest and greatest. Honestly, I did not believe that it would be able to 1-step correct but I am eating my words right now, literally, as I am in the middle of the job. Using spotlights and sun light, the swirls and RIDS are gone and there is ZERO buffer marks or holograms. Even with SIP I would get holograms on my dark colored cars. I can't believe it! I am going to finish the car with FG400 and go straight to sealant and wax. I would give it 6 stars if I could. I am not even using a high power machine, just a little old PC 7424 (the original) with a 5.5" uber orange pad. Speed 1 to spread, Speed 6, 2 minutes or 6 passes with 5 lbs of pressure backing off to machine pressure and increasing pass speed to burnish to a gloss, and my word does it do the job.
