Last year I discovered a Meguier's spray on hybrid wax / ceramic product. I started using it on my vehicles. First time it takes two applications. First application spray on when car is wet, then dry car with polishing rags. Then wet car, spray wax on again, let sit a few minutes, then rinse off from top to bottom and dry with polishing rags. Lasted for 4 months, then all you have to do is the second spray on wet, rinse then dry.
I used this on my boat mid season and it was still shiny when I took it out in November. Saturday I am going to wash boat, buff out with cleaner / wax, then do the 2 coat ceramic hybrid spray wax thing. After that, next season, it will just be the spray wax thing. much easier on my old body.
