I'll be doing that myself sometime soon I think, doesn't look like I'll ever see a chrome set up for grabs.
Looks like the Dia-Compe logo is stamped into that caliper though, rather than a sticker?
Or has the sticker just been bleached by the nitromors?
Yeah, even a tiny speck burns like crazy if it lands on you. I soon learned not to scrub at a frame with a toothbrush when it's covered in nitromors
