Shifty shift...

I am going with an old 9sp XTR rear derailleur. Durable and light with enough capacity to accommodate a double up front if I ever choose to go that way.  But, what color are these things?  Aluminum and bluegreyblackgunmetal? Why not just make it aluminum and black?  Better yet, just polished aluminum.




Its has an anodized surface so paint stripper is not an option.  Sanding is an option but would be difficult and would leave all the impossible to reach spots untouched.  Time to call in a chemical strike.

I have read several sources that say that a lye based approach will eat away an anodized aluminum surface.  Specifically, many have used Easy-Off or Greased Lightning.  I went with Easy-Off because it was available.

I thought I would just test one spot...


But got impatient and hosed down the whole thing,,,


The result after 25 minutes and rinse...

After second 20 minute soak to get some of the remaining spots from the derailleur body...
The results of the Easy-Off treatment look pretty good.  I'll now apply some buff and polish to see what happens.

 

Oooo... shiny.
