This is it, on the right (many thanks to rsloman over at the coupe club for this awesome picture at the meet last weekend)

So I think I'm going to try to keep it clean

Any tips on stuff to get before I nip to tescos at midnight? Bear in mind I usually have to park a fair distance from my house, often in the next street... I usually wash it using a bucket of hot water and Turtle Wax shampoo stuff from a clear bottle (doesn't leave white streaks), and rinsed off with a bucket of cold water literally thrown at it
In particular I want to try to get some of the muck and brake dust off the alloys. How do I do that without tearing the sponge to shreds?
