I spent the better part of the day last Monday and detailed my cousins M3. Some light buffing you get rid of swirl marks and scratches, used surface prep and ended with Adams Ceramic Spray coating. Love this product, so easy to use and amazing results. Application is straight forward, used a grey microfiber applicator, spray product in applicator not directly on car. Wait 2-4mins for product to “rainbow” over and hand buff with MF towel. Worked in one section at a time. Adams claims 4hrs of total cure, I waited 24 to touch final product and you can feel what is the ceramic “shell” and the deep gloss is absolutely apparent. I wish I could post the vid of the water test and the hydroponic action of the product.
