Yeah, Tim's a sound bloke and one of our top approved traders on Detailing World
As for the polisher - are you sure you want the G220? It's reliability record is appalling (although to be fair to Meguiars they always change them under warranty). You are paying for the 'detailing' name and a fancy plastic case with this machine in my experience - don't get sucked in by the brand name
I know he's out of stock of them right now, but consider the Kestrel DAS 6 kit with the Menzerna polishes & pads. They are the best polishes on the market right now imho (and others) but you'll just need to add a finishing pad to this kit

Something like the Meguiars 'tan' pad or a Lake Country 'Black' would be great.
