Yes Scratch X works a treat but, like redfox said, you have to rub damn hard. I did 2 commodores in one day, then waxed both that night (carnauba wax - amazing!). I was soooo buggered! (I'm only little

) My wrists absolutely killed at work for the next week cos I had to do heaps of lifting and stuff
Anyway...this is just to warn you
Next best thing is a professional job
Thanks for the tip Julie! I'll have to try it
