So now that I don't trust my dealer at all I am second guessing his advice on caring for our slide outs. Advice given was the gears to the slide need to be greased and he recommended this very running type grease. I am sorry I don't remember the name. He also said the we need to apply a foam protectant to our slide seals and again I don't remember the name of the product. Is this advice correct? Is there certain products you guys recommend? How often does this need to be done? I apologize if this information is in the manual. I left it in the camper that is 2 hours away. I am just trying to figure out what maintenance we need to get done when the weather warms up.
