I received a few samples and really like the clover SCG 6525. The sample has an adhesive on it so I assume that is what the product uses to adhere to the window and this model number is not a static c

Yes, it has adhesive and is not a static cling. If you ever need to remove it from the glass, just peel down on an angle slowly from one corner and it should come of cleanly. It will stay on the glass well until you decide to remove it. Cleaning down the road will not affect its adhesion.
