I have a number of tubes of Loctite RTV 598 Black Silicone. It states that it is low odor and non-corrosive. Does anyone know if this is similar to, say, the Permatex brand sold by DXEngineering? I see that Summit sells both but DXE only offers the Permatex brand. Looking at the MSDS for each they appar similar but not identical. thanks in advance. Phil N9LAH
