Just bought my first steel frame (well, since the 80s anyway), and was wondering if I should bother rust-proofing or not? Planning to keep it indoors/avoid rain etc, so thinking maybe not necessary, and don't really want to mess around with Framesaver and similar products. Would WD-40 sprayed inside the frame does a similar job? Also, anyone know if CRC 5-56 commonly available in Japan is the same or similar to WD-40? Cheers in advance!
