Well, I don't know...I've seen videos of a number of different clays being used - they all seem to use the same method...looks easy...I have no idea what I'm doing wrong...
At the time when I was getting clay deposits sticking to my paintwork, It was summer and was pretty warm, AND I was using a halogen lamp above my car...I think maybe it was too warm for the clay and so it was kinda melting...the clay seemed hard enough, but the car's surface may not have been cool enough...
Anybody have experience with clay bars who can help?
