Yup powder will definitely mess up your threads. When I do them I wrap the threads with foil and powder the head part only. [thumb]

Thanks for all the resources everyone...I will go looking this weekend.
One question left- (I have powdercoated some bolts with the technique Steve mentioned-covering the threads with foil..) is it ok to spray paint the threads with say rustoleum? or better to just put some of the rust preventative stuff on there and leave it like that?
Depending on where they are, you may be able to install them and then spray them with paint, or undercoating, from the back-side.
For stuff I plan to keep bare metal I spray them with Boe-shield, which you can get from Tacoma Screw and other places. Not quite like cosmoline thick, but it is what Boeing designed and uses to protect airplane parts from rusting.
