help! pinholes in my plaster castings

Help! I sculpted a bust for my client, made a silicone mold of it, and am to give him four hydrocal casts. These casts have been curing for the past week and I am polishing them up to deliver them to him tomorrow. I was blowing them off with compressed air and now I come to find all kinds of tiny pinholes!!??

I'm freaking out...does anyone have any suggestions on how best to fill them?
