re-coloring aluminum(14 posts)

re-coloring aluminumwooden legs
Jan 26, 2004 11:36 PM
seeing as most people here seem to have plenty of experience making aesthetic alterations to their bikes and components, i was wondering if anyone has ever tried to stain or otherwise color aluminum. i have a sugino mighty comp track chainring that came in "champagne" color, which apparently translates to a sort of vomit aged greenish yellow. i scrubbed off as much of the anodization (sp?) as i could with steel wool, but it's still a bit yellowed when you put it next to alum crank arms. i'd like it to look the sort of gunmetal grey that my sugino 75 looks, was thinking that maybe a stain of some sort would work, but have no experience. normally i'm function over fashion, but i've put enough hours into repainting my fixed frame and matching bar tape and finishing tape and tires that i'm not going to stop on the last components to be added before riding. thanks for any suggestions -

I use drain cleaner to remove anodizing. Just wear gloves.

The arms can then be polished with any metal polish. As for adding color, it is expensive to anodize. I've tried paint and it doesn't last. Powercoat is an option but it would also cost too much just to do crankarms.

If you remove the anodizing. I suggest, you just polish the arms.

This seatpost had the anodizing removed and polished by using the above method

The arms will turn black after sitting in the drain cleaner. Don't worry, it polishes right out. I bought some superstrong drain cleaner at Home Depot. The bottle comes inside a clear plastic bag because the stuff is so strong. It only took about 5 minutes for the anodizing to start bubbling off. Regular Draino(sp?) can take up to 30 minutes to work. Don't leave the arms in overnight because it can cause pitting.....

copy that. i'm actually doing theis to a chainring, so i;m not letting the draino sit for very long, definitely don't need any pitting especially around the teeth. any suggestions for polishing with normal household items? i don't really have an extra few bucks to go out and buy metal polish. thanks-

It has a very mild abrasive and works wonders on metal

Do you have pictures of every component on every bike you own, or do you just have a digi-cam and quick access to all your bikes? Whenever someone has a question about a component or bike or sticker on their vehicle, you always seem to have a picture that fits the answer perfectly. Either you are very anal about cataloging your equipment or you can run out a take the appropriate picture whenever you need to.

I'm not slagging you, I'm just curious how you always have the right picture ready to post. It's awesome!

Honestly, I take a picture when someone asks a question but over the years, my file has grown because of so many repeat questions.

The only new picture in the last month was the back of my vehicle. All the other pictures were taken out of my old files.

Dave, how long does that polish on that seatpost last? Once the protective coating is removed, does it oxidize quickly and require monthly polishing?

It had a very heavy coat of wax on it and is fine for a couple of months. The only time I really need to polish it is when I remove the saddle bag. The finish gets pretty dull underneath the saddle bag strap

Everything you've always wanted to know about home anodizing, plus he will sell you the stuff to do it. Never tried it but looks pretty neat and fairly easy. I think you can even anodize over an already anodized part but you might not get the color you're after.
