I have decided to use the perfect shine system outlined on this site. I just have a few questions. I have heard that Klasse all-in-one is hard to use. Is there an alternative that will give me the same durability? Also, I will be using the P21S paintwork cleanser, will this remove small scratches? Will it thin my clearcoat too much? And finally, I have decided to use Einszett polishes to remove scratches after wetsanding. Are those polishes good? Also, if I have waterspots that will not come out with the paintwork cleanser, will it be safe to use the Einszett polish on the whole area with the waterspots? Please help!
