Kirikuchi is for ? species

Hello all!
I just picked up some Kirikuchi, I am wondering what species to use it on, and NOT use it on.
Atlas Cedar? Pine? Cypress, etc.

Are you talking about the cut paste? :thinking:

Yes,wound sealant. Anybody has experience using it? There is any species whereby shouldn’t be use? Michael Hagedorn mentioned briefly during Mirai (pear tree) super critic.
