for a wax, i would recommend dodo light fantastic which is a soft wax, or dodo diamond white (quality name) which is a hard wax and would probably have better durabilty over the light fantastic, although softer waxes are easier to apply/buff off normally.. there are many shampoos on CYC so it just boils down to cost really as they are all good, also tim (guv @ cyc) is a top bloke and i recieved an order today in top condition and well packaged - i ordered it on the saturday just gone, but if you order on a week day, it should arrive next day..
hope this helps and happy cleaning
