Was speaking to my brother-in-law today, asking him if he could get me some touch up paint for rear bumper.
(he is the boss of the bodywork shop in local vauxhall dealer)

Was talking about polishing up after paintwork; and he mentioned
a product called Sonax.
Said he buffed up a wing of a customers car, as some mech had left dirty paw prints on it. Owner couldnt believe it. Said it came up like glass.
I'm going to try it out; if its as good as wax wizard it'll do me.
Apparently its new to UK ?? must be able to get it at vauxhall dealers.
