Do I stain/finish the bottom of a bookcase?

So I got into a project recently where I've been using general finishes gel stain and topcoat. Goes on great, even on verticle surfaces. But then I notice a 30 day cure time.

I'm sore about it already, but realized I can't finish it all at once. The bookcase is heavy as heck and if I can't set books on the shelves for 30 days, I sure can't set it on my hardwood floors for that long. Do I:

A) finish all visible surfaces, and leave the bottom unfinished

B) finish all visible surfaces, wait 30 days, flip and finish the bottom... Losing some capital with the wife due to 30 days extra delay

Or C) seal it some other way, and what would you recommend?
