Hello I have a question regarding this spray. I washed and cleaned and dried my cars and applied this coating on them about amonth ago. It went on and off so easy and they looked beautiful. Now this past weekend I washed them again and I wanted to apply the ceramic spray coating again but I noticed on the hood of my truck it left swirls and was really hard to get off and on doors it felt like swirl Mark`s. It also did it on my car as well. I thought maybe i hit a coner that had a lil water still idk what it was from. What could it have been to make it not like easy to wipe off. Any information would be appreciated I also have follow up question after this gets answered.
