Sue, I spray them after affixing the label. Also I usually spray a couple light coats allowing them to dry in-between. I'll have to see about getting some pictures of mine. I actually dated a few of them last year on the backs of the plate. A mini experiment to see just how long they will go before needing replaced. Trouble is, I cant remember which ones I dated...
I guess I will have to look at the backs of each label until I find them...
