I have been riding around on a converted circa 84 peugot road bike for about a year and the frame has taken scratches, and has a bit of rust as it is 30 year old steel. I was planning on painting the frame and while I`m at it I was wondering if it would be possible to remove all the pieces protruding from the frame as they look ugly and I dont need them. (By this I mean cable leads etc sticking out of the frame) If I took these off with a grinder could I fill in the holes with some sort of molding putty before I paint it. Any advice
