Souveran Paste on Silver
Let me first warn this is PERSONAL PREFERENCE:
I dont particularly like P21S/S100. It beads well, but contains alot of beeswax which does nothing for the paint, it just makes it bead well. Easy to use but no-where near Souveran. Souveran is hands down still the best looking carnuaba, and so easy to use.
Durability and carnuabas are not necessarily words that should be used together. While carnuabas offer superior looks through depth and wetness, they are relatively short lived products. Under 8 weeks. You should look to a paint sealant for longer protection, or use something like Crystal Mist from Pinnacle after each wash to keep a carnuaba going as long as possible.
As for silver and greys .... I find that three paint sealants look well on it. Wolfgang, Klasse Twins, and Four Starr UPP (oh how I miss the') . These will offer 12 weeks of protection and offer gloss and reflection. I find most/all paint sealants slightly sterile so I use alot of gloss additives weekly. Clearkote Quikshine , Finish Kare 425, Sonus Spritz, and Four Starr Gloss Enhancer.
