anyone ever painted a rim? i've got a couple lying around that i'd like to try it on. since the rim is adonized, i would imagine the process would be different than painting a bike. does primer stick to adonized aluminum? any suggestions?

de anodizing a rim could be quite a PIA. i think that if you sanded and primered it youd be good to go if youre looking for something that is ok quality and not meant to last for years to come. i spray painted an old 80s wheel last fall light blue and rode it for a couple months and it held up and looked decent enough. here is a crappy picture of it right after i initially assembled the bike. http://photos-a.ak.facebook.com/photos-ak-sf2p/v130/158/95/1800119/n1800119_34335992_3561.jpg

actually it's incredibly easy (off :D)
all you do is get some easy off or other oven cleaner, then follow the directions on the can for a cold oven and pretend the anodized part is the oven.
ok now PAINTING bare aluminum is NOT easy,..well actually it's easy to paint, it's just not easy to get paint to STICK,..... your probably NOT going to be using anything in a rattlecan and expect it to last more than a week on a wheel.
so I recommend using an aluminum treatment like PPG DX533, followed IMMEDIATELY by using a 2 part epoxy sealer (PPG DPLF, or MP170 or others), THEN you can relax,....wait a day, and then paint with whatever you like.
aluminum will start to corrode in MINUTES after cleaning, the DX533 gives you a little more time (maybe a half hour), so getting the aluminum coated with the epoxy before it starts to build a layer of oxidation is tantamount to success.
there is one cool @$$ thing I have been wanting to try:
House of Kolor makes special candy tints (KK series concentrates) that you can tint any clearcoat with,
then there's this stuff which will stick to ANY METAL POLISHED OR NOT: http://www.por15.com/prodinfo.asp?grp=GPC&dept=6
so you strip your wheel, then sand and POLISH it, so it looks super shiny like chrome,........then mix your favorite color KK candy tint in the glisten PC, shoot the wheel with the candy paint and you have blue chrome wheels or whatever color you chose and HOK makes about 40 or so candy colors. (planet green with a touch of rootbeer looks JUST like british racing green)
the resulting finish would look very much like this:
I've never seen that on a bicycle yet
there ya go, you can start trends before anyone knows it's a trend. :p
