I took delivery of a 2016 Laguna Blue Stingray Coupe a couple of weeks ago. I applied one coat of a competitor brand polish, names begins with K and it's a German product. I followed this with 2 coats of the same brand of paint sealant. I want to use similar products from Adams. What would you advise and what do I need to do to prepare my car for their use? Thanks from a Newbie.
