Depends how big the dents are, and it might affect the strength of the tube if you are going to ride it.

Post by: SteveG on March 02, 2009, 11:00 PM: I forgot about brazing. Probably safer, I just used the welder as I have a mig already.
One thing to watch if the dents are big is that they will probably have mis-shaped the tube. I can't explain it easily but where the dent goes in it forces the tube out either side of it. Not quite sure how you could do it but it might be possible to pull the dent out.
