I want to remove the black ano coating on the set of Rolling Darryl's I have. I tried paint stripper (like aircraft remover) but that didn't do anything.
anodising is a process the hardens the surface of the aluminium, the colour is impregnated in the surface during the process. You have to physically remove the surface and need to use an abrasive tool to remove it. I would live with it or sell what you have an buy the colour you want.
 
Have I not seen EZ-Off used very successfully for this? I believe Mendon Cycle Smith had pics posted of this very recently. Or... am I wrong?
 
Basically, you just need some form of sodium hydroxide. All the products mentioned here are sodium hydroxide based- aka caustic soda, lye, Drano, ect. Watch out for the fumes, and make sure you rinse the parts very thoroughly afterward. Sodium hydroxide basically corrodes the anodization away, and it will continue to corrode the bare aluminum if not thoroughly removed or neutralized.

In case anyone is not aware, anodization is not a coating- it is a layer of aluminum oxide that is induced to form on the surface of the bare aluminum. The same gray stuff that forms on un-anodized parts naturally, but it is a controlled process. Color can be added, and the oxide layer can be made harder or softer.

And most important, do it outside!

The fumes from the process, will corrode just about anything, and the few things it will not corrode, it with etch instead.

The best way is to look up a local anodizing house. they will strip it in a controlled environment and will ensure even removal.

Better yet, they can re-anodize it in clear and any common color - usually red, blue, yellow... and a couple "house colors" that might exist for larger local accounts. Or you could just take them away and polish them.

These would fall under a minimum batch charge. I would be surprised if it cost more than $70 to do just about anywhere, and in my experience minimum lot charges at an anodizing shop are more like $40. That'd be the likely total for both rims.

Since this would be a matter of them dunking the rims in the tank with the other stuff they are anodizing, it would have minimal impact on the environment. Plus you don't have to handle caustic chemicals.
 
Yep, EZ Off worked the trick for me.

Not a process free of mechanical interaction, but I'm quite pleased with the end results. Let the chemical do the work, rush it to your own detriment. :thumbsup:

If you're looking to make them a color other than bare aluminum, I believe you can powder coat right over anodization. (Others please correct me if I'm wrong.)
I plan to have mine PC and like any coating prep is key to a successful finish. Mine will be blasted first to ensure an etched surface for the powder. As for applying over the Ano I'm unsure about it.
 
WHY do you want to remove the ano?

(If you're going to DIY paint, remember ano is applied as a base for painting. Just remove the sealer first (I assume they use a sealer after the ano to close the "pores"). )
