Getting these marks after cleaning.
Using the following:
-Autoglym Blast, Polar and Seal.
-Not letting the car dry in between.
-Final dry with Autoglym drying cloth.
-Overcast day so no direct sunlight.
-Panels cool to touch.
It's worse on the bonnet, windscreen and front of the roof 🤷🏻♂️
Any advice much appreciated as it's starting to drive me mad as it's not the first time it's done this.
