I personally made a bracket to hold the wheel that had 5 studs so the holes were covered.

There is another issue you MUST be concerned about. Build up of material where the wheel contacts the drum. After powder coating you want to take sand paper to the edge that contacts the drum and sand it very thin or to bare metal. The paint will rub off and then lug nuts will get a little loose. If the paint is slightly uneven it will warp the drum causing the brakes to pulse. If I remember correctly when I put a wheel on the drum and check out of round I got .013" which went back to about .001 when I sanded the paint off.
