^ yeah degreaser/wax and grease remover pretty much the same thing. I used the degreaser from Repco which I found provided a very strong bond with the primer.
Also in addition to above, to get the best durability possible - the first sand of the wheels should be done with a medium grit, say 180, which will provide an abrasive surface for the primer to 'cling' to. Once you've primed it, wait for it to dry and lightly wet sand it with 600-1000, making sure you don't sand off the primer. Hit it with wax and grease remover, apply another coat, then repeat with 1000-2000 grit sandpaper. Then apply color/ clear.
