I read somewhere here I think about JB weld putty. Not the 2 part tubes red cap and black cap you squeeze out but a putty with both parts resin and hardener in a plastic tube. I found it at advance auto. You slice the putty like cutting butter and mix the two. Then spread on the wheel and allow to harden. Then I sanded to shape and that was it. It has been on the wheel for over a year.
