the charge is strictly for the adhesion of the powder to the metal before curing. It is a very durable and secure surface as Philip observes if the proper prep is acheived, and a lot has to do with it's adhesion, polymer constituents, and encapsulation properties.
It is commonly either boiled off or chemically removed in commercial
application.

I have removed it mechanically by both sander and sandblaster. a bit more effort than removing paint.
you can paint over it.
I am currently experimenting with masking and resist applications, this is a bit more difficult than paint due to the curing temperatures. Gradations are less predictable as well, there is color shift in the curing. the simple effects of texturing and veining expands possiblities in powdercoating. -- gabriel l romeu chesterfield nj usa ± http://studiofurniture.com Ø http://journalphoto.org ±
