I need to get my wheels powdercoated, however I have been advised by the company doing the work to remove the six rubber drive dampers - cush drive rubbers from the rear wheel as the wheel needs to be heated to 230 degrees in an oven to bake the coating. I have tried knocking them out with a socket and hammer but they are not moving. I'm loathed to spend out nearly ?80 in new ones. Has anyone had their wheel coated and left the rubbers in place, just concerned that they will melt in the oven.
