Awhile back, a few guys I met at the baytubers tournament wash their kayaks right at the parking lot with portable sprayers and mounted truck undercarriage sprayers. I was intrigue and tried to do a search but nothing found. Anyone else doing the kayak spray down before they hit the road so by the time they get home the kayak is dried and ready for storage? Here's one of the product that i'm talking about but i'm trying to do a 12v direct plug from the car with a switch and mount this under the car, but 4 gallons of water seems so little.
