Moisture issue and repair

Got a call to fix the floor that is peeling along the expansion joints. I wasn't original installer,but it wasn't installed more than couple years ago. As we started to peel whatever is loose, kinda got obvious that all the moisture that runs inside the joint, pools up and because inside of it wasn't coated at all,that moisture repells the flake with base coat ,only couple inches away from the joints.The rest has good bond. Customer also said he is washing the car there all the time and there's a good slope towards the drain, but whatever water gets in the joints just sits there ,dirt being soaked also inside of it. Would you cover the joints all together or just clean it up, let it dry and coat the inside of the joint, just to seal it? I told him I can blend the patches in as good as I can, he doesn't care if it looks a little different, but my concern is that it doesn't happen again more than esthetics of it.
