I have a 01 Lemond Buenos Aires. Its 853 steel. I've decided to apply some framesaver. I know there's a bunch of posts on applying framesaver, but none seem to answer my exact question. That being: There's already some rust in the frame. Nothing major, more just a surface rust color. I can wipe it out pretty easily in the BB and seattube. However, it may be in some of the other tubes. Can I just framesaver over this? Or do I need to somehow wash out the stays, downtube, etc.? I just don't want to lock in evil rust. Thoughts?
