Collinite 476s
Or any of the collinite range
Do you find the 476s lasts long? I had a tin years ago and remember being impressed by it. Lasted ages and even stood up to TFR etc. Being Detergent proof.
Got a tin more recently and to be honest it doesn't seem to last a crack! Water runs nicely off tbe car for a couple of washes and then seems like it needs another layer!
