Review on Chemical Guys ACC_M04 Monster Merino by Drexel Wortham

I bought this because our new Tesla is covered in pollen literally every day which helps not to spray as often and to wipe but i wish i could that the bag has a zip or something because it just sits in the supplied bag in the trunk and looks a bit dirty and probably spreading dust. also one of the times i shot it i think i must have moved it wrong or something and the stick broke so i had to glue it together now its quite brittle. I'm worried how long I can use it before it starts scratching the thin paintwork on the car.
