Hylomar is not like any other Permatex product. Actually it is just sold by Permatex under license in the USA. It was originally developed by Rolls-Royce Aerospace Division for sealing joints in jet turbine engines. . It holds up very well in sealing against oils, all types of fuel, hydraulic fluid, and, coolants. It never dries out.
But it's definitely not useful for sealing up the end gaps.
