I keep my bathroom countertop relatively clean at all times, but it is a challenge because I use hairspray on a daily basis. Even though I know it's clean, it does not have the shine that it used to. When I used this three part kit with the ceramic coating, I was amazed at the difference it makes in the appearance. When I was finished, there was a glossy look to the countertop that I hadn't seen in years. I'm using the maintenance spray to protect the coating and to keep the shine ongoing. This kit is definitely worth the price when you consider how great the improvement is, even on older surfaces.
