I seal year round. It keeps the moisture out in high dews, and the moisture in during low dews. I use sweet almond oil or jojoba oil. I'm lazy...I emulsify it with LI in the palms of my hands and scrunch away! I am also low porosity, so I add a bit of mousse after the oil/LI, and I let it soak in for about 20 minutes, then add gel (which I emulsify with a bit of curl cream) and diffuse a couple of minutes. Being lazy finally pays off!
2c/3a, fine, low-med porosity, below BSL, mod CG since 9/09
