For the first few seasons after getting our new Classic the white roof coating seemed to "bleed" off and down the sides of the trailer, turning to a chalk like substance when it dried. It's slowed down considerably the last few seasons.
I just scrub it down now at every Spring get ready. It doesn't seem to be waring thin but its something I keep my eye on.

So when is this..."old enough to know better" supposed to kick in?
