I had my best Nervex-lugged bike powdercoated about 15-20 years ago. The durability was great; and, unthinking, that is what I was after at the time. But the moment I committed to reviving the bike to its classic nature, I rued and regretted my shortsightedness. I opted to sand down the frame; but the lug edges were a nightmare!! I even pulled out the Dremel in a fit of anguish. My advice is to shine-on powdercoating in the case where the classic frame has value to the bike.
