Taking the previous recommendations for Autoglym super resin polish for the roof and and Carnauba Wax for the sides I was gob-smacked to see that the Carnauba Wax can cost up to £795 a tin

I found Simoniz Carnauba wax in my local car store for £8 and it does just the same job as putting on a protective layer of wax with a shine. I found that its best to work in small areas and then buff , otherwise it will dry on hard and then it is difficult to buff off.
