I wash our trailer periodically but I'm admittedly lazy when it comes to waxing it. :) As it sits on my driveway during the hot summer months the front and curb side are exposed to the direct rays of the sun for the entire day while the rear and street side are always shaded. When I have managed to talk myself into waxing it I've used
Nufinish Car Polish and although this trailer is a 2014 built in 2013 I've noticed no deterioration of the finish - seems glossy to me and the decals are holding up just fine. I guess Nufinish must work. :)
