"Super Walbernize" for the latter models. Am not sure from which year on - anyone know?
And yes, it does work miracles with small scratches. The first time I washed the FaN, I used a sheepskin mitt. I couldn't believe my eye balls - the mitt left swirls when viewed in the bright sunlight. Oh wow. Nothing like ruining a new trailer in the first wash.
Anyway, my dealer sells the Super Walbernize stuff and it elimiated all the swirls. The fleece mitt went into the garbage; the only thing that gets between me and the FaN is microfleece.
And yes, roof access is a big PITA. I am envious of the RVs with a walk-on roof and built-on ladder in the back. You have to get creative with those access solutions.
Right now I'm parked on a farm. I made my scaffolding from bales of hay (covered in tarp so they wouldn't scratch that precious clear coat) with a ladder across. It was still kind of scarey!
