The gaskets/seals/weatherstripping under my roof rails are starting to fall apart. I've used sealant to kind of caulk the gaps, but it doesn't look too great. And more gaps gradually keep appearing. I don't really know what these actually are, and haven't seen any posts about them. Are they formed gaskets? Can they be replaced, as in, unbolt the rails, lay a new gasket down and rebolt down the rails?
