Datsun Roadster Permatex Form - A Gasket 4 ounce bottle

Permatex Gasket & Freeze Plug Dressing USA 

Dressing is a brown color aviation dressing that many automotive engine builders prefer over the older automotive dressings like Gasgacinch. Bit higher price too. 4 ounce bottle with brush
Quite frankly more difficult to remove at later engine dis-assemblies because this is stout stuff. Requires the user to use the product sparingly as excess amounts will stain aluminum surfaces and be very noticeable. The only product I will use when installing freeze plugs ...it is that good. But then again what do I know?
