paint job. The type that is one color when viewed from one
angle, and a different color when the angle is changed. And
I have some questions about it before I decide.
1. I have only seen this on certain bikes (Cannondale?). is
it a patented process, therefore unavailable to the
general public? If not;
2. How expensive?
3. Can it be done "at home"? Assuming one has the proper
equipment (compressor, paint gun). How complex is the
process, and where could I learn how?
4. What color combinations are available? I would like
something like green/cyan.
Again, TIA

I can't imagine a custom painter not being able to do this.
Or an auto paint place should be able to provide it. At my
work, we have these types of pigments. They either come from
the manufacturer mixed in a base (e.g. Beckers from Sweden)
or in dry powders that we add to a clear medium.
The base color is critical for the effect, as with most
metal flakes. And the thickness of the coat is also
important. Getting a consistent thickness, within 1/1000" or
less, can be difficult on bike tubes.
I've used a little of the powder among other pigments in one
bike paint job. The flop is minimal and subtle. I applied a
urethane top coat- ChromaClear 7600 (two part, dangerous for
home use) which didn't seem to have a huge effect on the
flop. Beckers provides it own top coat which is pretty matt,
but I have no idea how this would hold up on a bike. I'm
going to test it soon for an upcoming paint job.
Basically, either have a bike painter do it- should be very
possible. Or talk to an auto paint supplier. Get a good respirator-
forced air preferable- and be careful. Some serious
chemicals in some of these paints, and metal powder is never
good for the lungs.
Be careful with these pigments- they can be eye striking but
actually quite ugly. As a guy I worked with said, it looks
like a couple of the colors you get in the bottom of the
dump bucket when mixing paints. Choose carefully and judge
it in sunlight.
