Hi everyone, I have a secondhand Dahon Boardwalk and I noticed some minor rust buildup in the frame (the bike at its folded state allowed me to peek thru the openings of the frame). What can I do to minimize the formation of rust? Has anyone tried Frame Saver for their folders? Also, can anyone recommend maintenance tips on maximizing the life of my bike? Would rust resistant coating on the exterior be ideal as well? What products can be used to remove rust? Not sure if the rust buildup in the frame is manageable without any action but since I'm quite inexperienced and therefore, paranoid after reading stories on folding frames breaking in half, any advice is appreciated! Thanks!
