The fork rockers are a little rough from the factory. I glass beaded them and had them powder coated and they look really nice. The welds on these bikes are not the prettiest; remember they where done 50 or more years ago with less capable equipment. I chose to reweld only one that failed and left the others untouched. This wasn't really a weld failure as much as from running into things with the crash bars and tearing the metal at the weld location.
I hear you on the originality, so I didn't smooth any of the welds either. I did choose to powder coat the frame and many of the parts for durability sake though, but I felt this wasn't too far from original to be over the top. AFWIW, powder coat is paint, just not liquid. See, there, I just justified it in my mind! LOL!!
