Here are a few pictures of the Pro-Line that I am currently working on. This boat gets a complete detailing each spring before it goes in the water. Then it gets a dockside detailing about mid-summer. So basically, all of the upper area fiberglass gets polished and waxed at least twice a year.
The best polishes and waxes to use are those that are dedicated for boats. I really would not recommend using any car products. Also, I am not a fan of using carnauba wax(such as #26) on fiberglass. For a last step protection, I perfer a polymer product, such as; Meguiar's Flagship Sealant. It is very easy to use and provides a good protection.
The steps involved in washing and detailing boats are much the same as with vehicles. You can figure that just about everything the owner would clean, polish and wax themselves, gets taken care of, including all of the exterior, interior fiberglass and all of the brightwork. Oh yea, the brightwork is the one exception when it comes to using carnauba wax. Once you get the railings and any other chrome and stainless steel cleaned, it is imperative that it then gets a top coat of carnauba wax. The carnauba goes on rather clear and does not leave behind any white residue. And carnauba helps protect the metal much longer than just using a metal polish. The vinyl upholstery and windows also get cleaned. Hey, I even polish and wax the stainless steel propellers. When you figure the cost of those props, it only makes sense to take care of that little detail. And you can bet that most boat owners notice things like that. That is the difference between cleaning a boat and detailing a boat.
Of course, when you consider all of the environmental factor constantly affecting boats, it is a good idea to apply protective products as often as possible. Almost all of the boats I take care of usually get done twice a season. Some even more than that.
