That Dow sealant is not meant to be applied outside the case seam.

You can purchase a dye made for oil. Add a little to your oil and it becomes very clear where the leaks are under a black light (ultraviolet light). I would much rather see you use this than a foreign substance in your sealed case. The only concern I have is that often case leaks only show up when the oil is hot and yours is not going to be for a while. Good luck!
