I filled in the stress cuts with a silicone based caulk, using a color that was close to the finished paint/coating. I would not fill these first and then paint as the 'caulk' may not be compatible with the paint, and the caulks tend to be soft, which will allow the paint to crack, chip, and peel. I used the silicone based caulk, so that when the concrete slab cracks (and it will) the flexible silicone will not crack, I am sure any hard fill will crack. JMHO.
