Step 5: Updates & painting your bookshelf!
I used spray paint to finish them. It only took a couple coats and worked beautifully. I didn't even have to use primer on them, which was quite nice.
I used a clear coat on top to help protect them from moisture. They are one of my favorite things in the apartment now. :D
And as for an update - they survived the move, and they're very, very stable. They've been full the entire time I've had them really. The only downside is that they're ridiculously hard to move around due to their weight. :P
