I used the Claymagic bar, and was very happy with the results. I don't think it is the bar, and I'm not implying anything by that, so don't take it the wrong way.
I used the Zaino car wash (Z-7) mixed with water in a spray bottle, I probably usd too much of it as the whole bottle was gone when I was done claying. All I know is the instructiosn said to keep it wet at all times and that is exactly what I did.
I need to do my Sister's Accord, it has been waxed
and is in need of some help, oh well Zaino to the rescue! Maybe I'll have some results and pics when the board comes back, hell I'll have nothing else to do!
