That's a paint cleanser (chemical cleaner polish). It's like the P21s Paintwork cleanser, but i prefer the P21s product. It will only completly remove swirl marks in the marketing man's dreams... It may help temporarily mask them though. It's not a poor product, but much like many expensive Swissol or Zymol products, i feel you can get the same/better results from much cheaper products. Swissol and Zymol can trade on their name quite a lot, and marketing hype.

I'd use either the Clearkote wax, or P21s.
