I use the Bike Bright stuff available at my local Harley store. $15 for a gallon and it lasts all season. However, I did waterproof the connectors after I brought the dog home. I've done this on any motorcycle I've ever owned. (Old man is has a masters in electricity, this has been pounded in my head all of my life). Also for those who have electrical woes after H20 drenching, before hitting the connectors with dielectric grease, get some CRC contact cleaner and spray. This will clean any corrosion that has formed and dry out the embedded H20. This stuff is available at Radio shack and any electrical supply.
