SILICONE SPRAY!!!!!!! THEY SELL IT AT ANY GOOD REPUTABLE AUTO PARTS STORE! Possibly even at Wally-World. (Not sure on that.)
I use the stuff on everything, especially on my cars and trucks, around the door seals, hood/firewall rubber seals, in the door latches and locks, etc. It works AWESOME.
Regardless, SILICONE repels water, AND it doesn't leave "crap" that will get all over your clothes nor will it collect dirt and gunk (like grease, vasoline, oil (WD-40, which also evaporates), etc.).
Silicone spray.
Silicone spray.
Silicone spray.
Oh, and did I mention, silicone spray?
LOL
Buy yourself a CASE of it and enjoy! (Seriously!)
