Yes, it will continue to spread, but it will be slow. It would likely take a very long time to truly affect the integrity of the frame from a structural point of view. While it's understandable that you wouldn't wish to remove any paint, it's the only way to go. You could treat and rectify the immediate area of corrosion and mask and paint small black or silver circles around the holes and they would look like they were done that way from the factory. I wouldn't let it continue to advance though.Do you think it will spread? Will it harm the integrity of the frame? I'd really rather not be stripping the paint off my pretty bike.
Anybody know if this would be something covered by the trek frame warranty?
