Because I figure "If I can do, it is highly likely that everyone else has already mastered it", I rarely ever post anything resembling a "how to" guide. But Doug asked this question in the comments of my last blog post...
So, what method do you use to get the labeling off the rear derailleur? I've been wanting to remove the "Ultegra" from my Ellis derailleur. Wasn't sure how to do it.
Well, Doug, I'm not sure how to do it either. I think I read somewhere about the stuff you see in the photo above, found it in a hardware store, and tried using it on something. It seems to be useful stuff for very light polishing. For example, I peeled the VO sticker off my fenders and a sticky residue was left over. I took the fuzzy stuff and polished it right off. When I marked my fenders with a Sharpie and had a few stray marks to clean up, the fuzzy stuff performed well again.
So why do I hesitate to answer Doug's question with authority? Shimano component logos seem to be much more stubborn. If you examine the final results of my "105" removal closely, you'd see that a vague "shadow" (I'll call it) is still slightly visible. You'd also see a difference in the finish in the area I did most of the rubbing as compared to the rest of the part. Maybe Shimano has some kind of clear coat finish on their shiney components or something. It took probably 20-30 minutes of consistent rubbing to get to what I deemed "done". A lot more work than the two examples provided above.
I'm not sure that I'd recommend using this same approach to everyone. But for me the results were satisfactory. From 5-6 feet away, it looks like a shiny label-less component. Since my bike is never again (Sorry, Mitch) going to look like a showpiece, that totally works for me. But it might not work for you. Anyone out there got any other suggestions to help me and Doug with future logo removal projects?
