Yea it sucks BAD!! But we greasing and anti-seizing the hell out of everything so when I do the long arms next winter it should be a breeze. Lol I guess 13 years of winters in Pa where they use nasty shit on the roads I'm luck it only has rusted bolts and light surface rust.
On a side note, what in the hell would cause a bunch of surface rust spots on the roof? There's nothing else like it anywhere, just the roof?
