Hey a guy gave me an old Mongoose IBOC comp just like the one I have, problem is that it has been outside for a few years, no seatpost or grips and the shifters will need some attention, but still work kinda anyway. My question is the frame, it's 7005 aluminum. Will the weather have destroyed it by now? I know the weather isnt as tough on aluminum as it is on steel but it does have me wondering.
