Ok had the CLK 3 weeks and its done nothing but rain. Dry day today so decided to clean her (after first fixing the ashtray lid and the passenger door speaker grill). Washed, clayed, polished and wax and wow....as new (bar a few stone chips on the leading edge of the bonnet). OK i'm not going to tackle the stone chips until the weather warms up (obviously) but the car looks amazing. I've never used clay before and couldn't believe how much engrained debris it pulled off the paintwork!. Autoglym SRP sorted most of the small scratches and the top wax of Mer added the deep shine. Pulled up at my local CO-OP earlier for a bottle of wine and a Golf actually stopped in the middle of the road and jaw dropped at the CLK....says it all!!
