used to be called the "racer's paintjob"...get a new frame because this one is "getting soft". I know a little more about metallurgy nowadays; don't you believe it. If a steel frame "gets soft" it is because it has a crack in it somewhere. Steel has a good fatigue life, titanium too, except for chemically pure grade. Another matter entirely for aluminum, which has no practical fatigue life at all (something to reflect on next time you're watching the wings go up and down while you are flying on a 757).
