I was wondering what you guys had to suggest about car wash shampoos. I've used P21S on my old car, but I was wondering what else out there is really good. I've heard Sonax was pretty good from one place but does everyone else think?

 

Alot of people in this forum seem to be using Zaino (including me) and I am using their Z-7 car wash and my opinion is that it's the best car wash I've ever used. Granted, I am no expert but this soap really suds well and cleans the car very nicely. Hope this helps.

Regards.

Keep using the P21S, its great stuff.
