While you're at it.....run a tap down through the 2 (or possibly 3) holes in the wheel to clean out the threads so that the next time you need to pull it, you can use a steering wheel puller, and you won't crack the repairs.
Secondly, I found that plain old vinyl spray paint, like the kind you use for changing colors on vinyl upholstery, works great for finishing off the color coat on a steering wheel. I prefer a brand called SEC which comes in a variety of colors and is found around most every body shop. I've had my wheel repaired (JB Weld)for a couple years with no cracks or paint flaking.
