Cheers young man I appreciate your guidance.
Apologies your right I've been using the 203S for light cutting along with the Tangerine pad. I've been selecting about 1/4 of the bonnet as my area, then having applied the polish I do 3 passes (a pass = Virtical polishing the area then horizontally polishing the same area)
So I assume I could either do say 6 passes or more, or buy another suppliers medium cutting pad and polish (assuming their suitable for soft paint) for the slightly deeper scratches.
As it happens this requirement isn't for my gunmetal car, which doesn't seem to show scratches to readily, but for my daughters friends car who has a black Vauxhall VXR which does.
Are you working the compound long enough/hard enough for it to break down?
The Menz should break down to an oily haze if I recall correctly. I don't recall how many "passes" I would have done, i judge by the visual changes in the actual compound.
