Terry, can you put the make, model, and year of you RV in your signature. That way we all will know what you are referring to when asking a question.
Thanks.
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.
What is 303 Aerospace Protectant? 303 Protectant is a water-based proprietary formula that contains no petroleum distillates, alcohol, mineral oil or harmful silicone oils.
