Zinc-Chromate Conversion (Passivation) is what you're looking for.

For the brave, you can do it yourself: http://www.caswellplating.com/kits/zinc.htm

Also, check around to local plating companies. This process is extremely simple, and you just throw a bunch of parts in a bucket with solution. No difficult prep or whatnot, just roughing up with a wheel before the zinc dip.

Yellowducking also had some parts done up for his RedBull build. Might want to ask him.

Found a guy in New Jersey who is a VW nut and does yellow and rainbow zinc plating. Lucky find!

I do!

If you lived local to me I'd replate your small parts for a small fee. But you don't.

I brought a small 4lt zinc plating kit some years ago. I've been zinc plating various original parts on my bike for about 6 years now. Prep is not as simple as just a wire brush. For a decent finish the parts need to be chemically clean. But as said above, it's not hard. Once plated off in the bath for about 45 minutes cold water rinse and passivate in Sodium dichromate (about 30 seconds dip) for the golden irredescent yellow chromate finish, rinse off and dry in the sun a few hours until the chromate is completely dry and hard.

All the zinc parts that I've done over the years are still free of any white rust.

I've recently brought a copper and nickel kit for those "shiny" parts.

A good hobby to have when I couldn't be bothered finding a company to do it for me.

There has been interest in this and I found a guy in New Jersey who does this type of plating. I have yet to use him, he is away for 2 weeks and will Email me when he returns home after vacation. I'll be sending him some stuff to do then.

Let us know how it goes. It'd be great to get some of the surfaces back to a near new finish.

What is this yellow zinc plating? Is that the gold color on the frame and brembo 3 spoke wheels on a 2000 machine?
No. You ever notice how some of the screws you remove have a yellow-bronzish tint to them? Its pretty much a different color of galvanization. It shouldn't really wear off but it does. I guess the best way to describe it would be to look at lets say... a rotor bolt. They're exposed to the elements like water and heat. Now pop open your tail section and take a peek at the bolts holding your oil breather expansion chamber to your frame. Those are how they should typically look when new.

I give terrible examples... sheesh.

Oh yeah I can vouch for rezincing steel fasteners and brackets. A mate has a 1994 916 which he took from looking amazingly clean to freaky clean by rezincing a lot of the nuts and bolts. $AUD20.00 or whatever for as many as he could take off the bike at any one time.

I had all mine done for the 998 I rebuilt, and I have to say it makes the job look worthwhile in the end for a very cheap cost.

Whats the cost exactly? I might as well send all my stuff out to get the coatings. Spindle, axel, motor bolts, other nuts, bolts, etc. Do they clean the parts for you as well?

Nice "MULTI TOOL" Too bad it's opening a Moretti Beer....The only thing I like about that brand is the label...Any Beer that has a picture of an Italian Drunk man on the label has my respect...
