Drilling hole in frame for galvy

My 88 frame is in great shape, no rust and still had factory chalk marks. I found a galvanizer to do the work ater I finish my welding my engine mounts but he suggested I drill some extra holes for zinc drainage. The question is where and how big to make the holes?

I pretty sure they would choose to hang it with the backside up, so the zinc doesnt pool in the rear cross member. I am just wondering has anyone had to drill holes in the past, where and what size hole did they drill.

I would think the existing drain holes and bolt holes would be sufficient. When I had a Rockware bumper dipped I drilled 5, 3/4" holes along it's bottom edge with one right at each end and that was a true closed beam.
