I have a black 2007 range rover sport and a silver 2005 VW passat. I currently use soveran on the RR. I am looking for a more inexpensive wax with the ease of application like soveran. The RR does have a gold metallic flake. I am very happy with the sov. But I need something for the VW. I am debating between PS21 and the sig series 2. ANyone with experiance in both can you give me any major differences. SS is on sale but would the ps21 offer a wetter shine
