I bought a '92 Paramount frameset with a unique paint job and found that the drive side dropout had been repaired with a weld that I don't recognize (TIG weld?). It doesn't look at all secure to me. I'd like to replace the dropouts but I'm afraid the heat would take out too much of the paint on the stays. I'd appreciate if someone could tell me if it's possible to replace without jeopardizing paint or if it can be repaired cleanly.
