I had this applied on my coach back in April, and my coach looks shiny new. I used this on my prior coach, so I have some experience with it. First application should be 6-7 coats. Less and you won't get the results you want. Every year you will need to apply 2-3 maintenance coats. Application requires following the prep instructions, patience, and a steady hand. I have been very pleased with the results. In between new coats just wash with mild detergent and rinse; I remove the road dirt with Turtle wash and wax, spray on, brush down, rinse off.
