1. You need a really good etch primer for it to stick. galv-a-grip or something like that is all I know that works
2. Galv
3. Never tried
4. You don't like silver?

thanks ron
Silver is cool but black is ideal.
for my sliders and steel rimms(the gal shop has a centrifuge)
then my LR winch mount then.....
it is actuall y cheap if you go in with a group.
our place is 150 cdn for the first 400 poundsor so....
anyone else have an opinion or tech advice? |

To make them black coat with undercoating, obviously not for wheels, I would not galvanize wheels, some have but I would not as I bet you would have air leaks.

powdercoat your wheels but not your sliders, anyone who uses their powdercoated sliders can tell you that they will chip once they hit a rock and chipped powercoat looks crusty especially when touched up with black krylon.
spray paint your sliders so when(if) you use them they can be touched up easily. and powdercoating gal. is a waste due to the fact that the prep. involved with powdercoating is sand blasting and the blasting would remove most of the gal.

Freshly hot-dipped bits can be painted immediately, even without the use of a metal primer. However, you have to be quick, because what actually protects galvanized parts is not the zinc, but rather the hard (and almost invisible) zinc oxide coat that forms soon after coming out of the molten zinc. It is this zinc oxide skin that makes paint adhesion such a problem. It has to be etched to give the paint some 'tooth' to adhere or else pickled in an acid bath to remove the zinc oxide.
