I just had my bike painted. Had it done at a rural body shop down the road from me that's scarcely even in business anymore. I think they just do an occasional auto restoration job.

Had a dent in the top tube which I did not expect them to repair. But I picked it up the other day and the dent was gone. I sure can't see any trace that might indicate they used bondo to fill it, but I really have no idea what they did. Looks perfect though, so it certainly can be done.
