I have an Offenhauser and it has no voids at all but wasn't a show shine polish job. I have the buffing equipment so I did a little work on it but not a super shine. You can see it in the link below.
Incidentally I bought it from Patrick's who has always treated me especially well. Fine people and a super Inliner
