Extremely concentrated foam, dissolves and softens dirt, I use it before the first rinse of the vehicle so as to remove dirt before washing with the glove and prevent scratches and "spiders".
Do not expect rich foam because this product is designed as a real active foam.
Attention: always in a shady place and always all surfaces of the vehicle should not be hot.
Dilution 1:10 in a foam gun

It gives a very good finish to the point where you don't need to go over it with another "hand" using a softer sponge

Attention to the application, not something extremely difficult, follow the instructions and you will not have a problem. Incredible hydrophobic, gives excellent gloss, this particular vehicle is 8 years old with daily driving in Athens.

In the 2007 Audi 2.0T, there was damage from the incorrect application of cheap polish. It was fixed with 2000 and 3000 grit sandpaper (very gently and with a lot of caution because the clear coat had worn off quite a bit) and then corrected and polished in one step using a Rupes yellow pad and Sonax Perfect Finish 04-06.
In the 2006 Corolla, it was corrected and polished in one step using a Rupes yellow pad and Sonax Perfect Finish 04-06.
The above does not constitute advice or instructions. Caution, those who have not used sandpaper on a car should not do so unless they are sure.
I have no commercial relationship or financial benefit from the above products, I just recorded my amateur experience trying to help other users of Scroutz.
