Sealing leaky Hatch Covers

Is there a “correct way” to apply 303 protectant to my WS Tempest hatch covers to help minimize water leakage during rolling sessions?

sparingly
just a very small amount on the inside of the hatch, wipe with a rag. Too much will make the rim slip off to easily. Even a Kajaksport hatch will become loose with too much 303.
