Okay, here is what I have used on my Seadoo 210 Challenger. I've also used their product for automobiles as well. It adds a depth to the finish with every successive coat you apply. I was skeptical at first, given that a 1 oz. bottle for a car is like $89 off Amazon. But if applied as directed, it coated my 2012 Mustang GT including the doors and jamb areas inside. I also applied it to my Sport Trac tonneau cover which is black, after I had buffed it twice to a high gloss shine. When I ran the applicator pad across half of it and buffed off by hand,,,it appeared darker and wetter and it was noticable. This is a Ceramic coating and near the higher end for ceramic coating products. Application is simple. Using the included foam pad, turn the bottle onto the pad gently wetting a couple of spots. Apply to an area about 2ft x 2 ft. . Allow product to remain on approximately 1 minute...then buff off with a clean dry cloth. You should be able to both see and feel the difference in the finish. DO NOT allow finish to dry on boat of PWC as it drys milky and is had to remove. One bottlr on a PWC should last you a long time if used sparingly. The bottle pictured is the Aqua coating designed specifically for boats. It is higher but is a better deal cost wise. It should last you for years.
Dirt and other messes just wash right off. After a 24 hr. curing period, spray it with water and it beads unbeleivably and doesn.t leave behind much water spotting at all.
This is my experience with it.
There are other Ceramic coatings out there, but this one was the 2nd best reccomended by a friend of mine who details for a living. It also is highly ranked online. There is another product called HydroSliex, which comes in a larger quantity and a bit cheaper which gets high remarks, but I chose this one because of the customer feedback and friends reccomendation.
Good luck, and remember the surface must be clean and free of any wax or sealant product. I applied mine after I had buffed it, then washed by hand to remove any residual compound.
Please let me know if you try a Ceramic coating how effective it worked for you!
