Service life of Collinite 476s max. two weeks?

Yesterday, after my last wax session of two weeks ago, I first washed and was terrified of how much dirt adheres to it and secondly, the water no longer pearls off. I describe now very detailed how I waxed two weeks ago and washed yesterday – the more detailed, the easier for you. (PS: with “wipe” I mean how often the MFT drives over the surface: so “three times wipe” = once before, back and before) Growing: Car with 0-8-1 5 detergents washed, kneaded, washed again and then removed the water stains with Arexons Aquazero Detailer. At about 15°C the collinite could be processed excellently. Allow the wax to be tightened for about 5-10 minutes and removed with a very soft Caress 660Blue. With the first/second wipe over the dried wax one noticed how firm it still adheres to the surface (the surface was dull). After that, however, the wax dissolved abruptly and the surface was pleated. Since you don’t see so much on white paint, I have repolished several times with medium pressure. Laundry: The car was not really dirty yesterday, but only slightly dusty. That’s why I made Fixe-7. Without wetting the car before I took down the dust layer with a Caress 660Blue and Shampoo-Water (Auto Finesse). The dust went away very well, of course, but there was a spot with a few little dirt splashes. For a waxed Surface was imho the effort of force too high to remove it (at medium pressure wipe about five times). Apart from that the water does not drain any more.
