I cobbed a protective cover out of neoprene for my Rugged intercom. The radios below are TYT and a Rugged TYT knock off which both have an IP67 or 68 water rating. The intercom is still OK After more than a few weather events and pressure washings. With any electronics ( even those with a rating) I would be extremely cautious when pressure washing.PCI claim any water-resistance? Would hate to remove for pressure washing. I had to do that in my RZR with off-brand clone radio. I know some Rugged kits have a faceplate cover for cleaning or when it rains.
