Depending on the roof you have, there are specific products for the roof. I recommend using them and following directions and using some sort of protectant. When it comes to the sides, many people have their own opinion on what works best. For me, I use a gentle car wash (like Meguiars), and I purchased a soft bristle long handle brush. Then I rinse good.
One thing I am particular about though is that I wax it twice per year. Its a long process, but the results are obvious. I use waxes designed strictly for fiberglass and/or gelcoat surfaces (like boats, RVs and truck campershells) like Meguiars M5032 cleaner wax or StarBrite Marine Fiberglass color restorer.
