Yes, Aluminum can be powder coated. P coating works on a -/+ method
where the frame is - charged and the powder that is sprayed on it is +
charged (or vs. versa) it clings to it and then is baked on. So almost
anything that can conduct electricity can be powder coated. (I wish
that plastic handles and bumbers were).
There are a number of threads that discuss p coating, so try a search.
I think there is even one from a guy who did his own (lime color) using
an old oven to bake.
Was told by people who know, that powder coating has far superior chip
and scratch resistance than paint.
Attached photo is my daughter's p. coated 20" freestyle. Though not Hot
Pink 'tis definitely pink. Note the dust caps on the cranks, they are
Aluminum.
Have been real happy with results so far (4 months). But, keep in mind
the uni is only used inside in a gym. The only real contact that the
frame would have is in unplanned 'crashes' with other uni-riders such
as practicing multiple rider routines (happens almost daily). As she is
an advanced rider (15+ hrs. a week practice) her feet are on the crown
of the frame about as much as on her pedals, and have noticed that the
paint is beginning to wear at the corners of the crown. Not chipped,
but wearing/rubbed off. Would probably happen with regular paint too.
Overall, no chips, few scratches that you have to look closely for
(graphics are taking a beating more than the finish) but do not have
any idea how it would hold up on Muni or street i.e. concrete, rocks,
etc.
