thanks Conker - it's Guy btw

i think Megs scratch x and AG SRP are two completely different products... i only use scratch x for smaller area problems... I used SRP for years and found it hard work by hand and also gave off a lot of dust.
gold class is great as a weekly wax.
if you are going to treat your paintwork try the megs 1,2 and 3 step polish system
AL - have you clayed your car yet? that's usually a very good starting point so that you can see what is paintwork problems and removed all contaminates like tar etc.
