Thanks, we've used toothpaste on her mask, we've also used a lighter which is way better than toothpaste. Her mask works fine when I wear it. We think it fogs up temporarily cuz her face gets hot when she sprints for too long. In fact, toothpaste alone barely worked on her cuz of that.
I'm glad you came to me about your buddy, you're a good friend looking out for him. It's too early to even know if Dana Point will be diveable this weekend. The spots I've been to in Dana Point are full of sharp rocks etc, I'm very comfortable in big waves & I wouldn't want to go there unless there's no waves.
Best thing to do is try to convince him to go with an experienced diver. An experienced diver will take him somewhere he'll have fun & keep him safe.
