I have the soveran signiture series wax (origional version not the series II) that I purchased late last year from them. The main difference is that this is truely a wax for lighter/or metallic paint. I sold my silver car and only have dark color cars, so I haven't used it much since (approx 7/8 left almost new). If interested, I would trade : my small wish list:
1) leather conditioners; from either
pinnacle, Z1, zaino
2) rubber/plastic interior cleaners or conditioners; zaino, pinnacle
3) natty blue
p.s. got some s100 for trade as well.
