:banghead I have been to several auto parts stores and have been unable to purchase "Silicone Grease". The manual states the importance of lubricating the rubber parts of the top and bed with silicone grease at least four times a year. I found a can of spray silicone but that's all. Any idea where I can get some of this stuff other than the dealership? Just want to protect all those seals getting exposed to the elements lately.
