Does what I need.
Size: Pack of 1 Style: 3 oz.
My pre-cats' (which are tucked inside the engine bay/compartment area, instead of the underbody) heat shields were rusty and loose after I did some exhaust work, and I needed to find a way to bind them together so they don't rattle every time I accelerate.

Great for valve cover gasket applications
