Very hard to apply, would be better with a caulk gun.
Great product, but make sure you've worked on your grip strength to get this out of the tube. I actually cut a fairly large application port into the lid and it still took all my strength to get this to come out smoothly. Additionally, the metal tube eventually broke in the process before everything was applied. It makes a fantastic seal though and I feel confident that my oil pan gasket replacement will last for the remaining life of the car.
