Jeeper: I use 303 aerospace protectant on mine as a lube and for UV protection, have not had any issues. I've heard some people use baby powder. You can go to the Lippert website lci1.com, support documentation section. There is a lot of information there, you can usually find the part numbers for what you need then Google the part number to find the best price if you need slide wipers. I hope this helps.
