No fumes. We do it right in our shop. Your wife dosnt have to worry. You do not have to cover the holes, you will just have to clean out the crap from inside them, but thats not difficult to do. 24 hrs is the minimum to get preformance back, but more is better.
U probably arent equiped to do this, but to get the best results, you ball should be sanded to 100 grit, or 220 grit sandpaper because it takes the oil off the surface and opens the pores for the product to absorb better.
