Due to some renovation work at my house and construction of a new garage, my car had to live outside on a neighbour's drive for almost a year. I have PPF (Paint Protection Film) on the bonnet and whole front of the car and it showed signs of wear and bad water spotting due to dust from the building work, tree sap, leaves and general weather battering. I looked for something that would help to bring back the lustre without causing damage. I found 'Gyeon PPF Renew' polish and was amazed at the results. I used it with a fine polishing pad on a rotary machine and the finish is better than when I first had the PPF applied. As I was applying 'Kamikaze Infinity wax' on the rest of the car I also applied this on top of the PPF and this helps with the gloss in the photos. Absolutely brilliant polish for PPF.
