I've been acquiring aftermarket hop-up parts for the past several months. Some of those parts included some gold anodized Option House parts. I'll probably disappoint a few purists here, but those won't stay gold for long.

I sprayed on some yellow-cap Easy-Off oven cleaner and removed the anodizing. This resulted in some charcoal-grey-colored parts. I wet-sanded those parts starting with 400-grit and finishing with 1000-grit sandpaper. I decided not to go any higher (it's possible to get an almost chrome-like gloss by wet-sanding with 1500, 2000-grit and then rubbing compound & polishing compound) because I wanted to make sure the anodizing sticks well.
