How does it cope with without first rinsing off the stuck on dirt? I'd have thought thatbtherevwas a risk of scratching the paintwork.
It does say on the bottles that you need to clean heavy deposits of dirt off first!
I recently bought some and it's very good. I have a dark blue Range Rover and waxing it is a lot of work, so I cleaned and dried it first and then used this stuff. It was the easiest wax I've ever used. Wipe it on, wipe it off. Which when you have panels the size of barn doors is a bonus!
When I eventually get my Morgan, I will probably use my vast stocks of Zymol....
