So begins my first fixed gear conversion project. Got a 1983 Miyata 310 and have begun to strip it..braze ons and paint, and some minor surface rust. (No problems yet with sandpaper, but may try stripper). My question though, is, what's going on on the inside of the tubes? As I look into the bottom bracket shell, I see lots of dirt and corrosion.. same with up the fork looking into the head tube. Should I be concerned about rust here? Do I need to get this cleaned up and primed before I begin to paint?
Thanks.
Many more questions to follow, thank you.
