Thanks for the comments
I know this test leaves something to be desired, but it's the only one we have at the moment. Hopefully there will never be a case where the opposite is true (product scratches CAR but not CD)!
A strange thing to note is that I've discovered Turtle Wax has reduced the size of their MF cloths at some point!
I therefore have two 16" x 16" cloths I bought originally, and the rest I bought recently are 12" x 16". This is a big difference (to me) since this is equivalent to getting another 8x8 cloth! I was kinda wondering why on earth I'd reported 16x16 before but now report 12x16...
I'm just happy people are reading because what they don't know is that they are reading copy number two! I was 95% done when my browser decided to crash.
Lots of anguish and cursing later, I calmed down enough to retype it faithful to the original.
