Looks like today was a perfect test for my weatherproofing. Raleigh was smack-dab in the middle of a rainstorm system and the downpour was briefly heavy at times.
I was elated to see when I walked to my car this evening that my Happy Mac was still happy.
The good news?
Happy Mac lives to see another day! The bad news? It looks like my sealer didn't
completely cover the bottom edge, as you can see some of the black Sharpie ink (that I used on the edge of the plastic) starting to seep upwards into the image.
Still, not bad for a first attempt!
I'm satisfied.
