Rusting Issues?

[Tacomac]

Hi there.
I was reading a review of the z400 on powersports network and there was a post about the frame welds, bolts, nuts, etc rusting fairly quickly on the z400. Does this seem to be a problem for anyone else? Also one guy told me he WD-40's his whole frame to prevent rusting. Would that not attract dust?
I am looking between the Z400, Ex400, and Raptor 700. I am a suzuki fan since i had a 50cc when i was 6. I just can't decide

Hey man... I've got three Z's and every one of the frames that I have found rust on... there is the starting of a crack. B/c it will crack near the weld and break the P/C, allowing water to get in and then the rust spreads, along with the crack. Just my 2 cents..
