can you powder coat stock valve covers and pi intake?

Dont bother calling them the plastic there reffering to is the powder its self if you look at there advantages page it lists the coatable materials which are all metel besides the glass. I have been powder coating for about 2 years and it is not possible for powders to cure at low temputres yet although our ppg sales rep says its a work inprogress so maybe in a few years it will be possible.
