Last time I posted a car wash topic, I went into great detail about the items I used etc but can't be bothered with all that this time so I shall cut a long story short.
I use mostly car plan products (including wonder wheels) and after a good vac out I duly washed and it, dried it thoroughly with a drying towel, cleaned the windows, sprayed the tyres with tyre shine and then deployed car plan triplewax polish. One slightly damp microfibre cloth to apply and a dry one to buff it off afterwards. Made mincemeat of what I thought were paint chips and blitzed minor scratches.
Hard work but looking good:
