Yup I have a love for little tree's, I have around 10 - 13 bonsai, most native, most collected myself. I love how slow the hobby is, and how it changes through the year :)
If its unlikely to be damp again, I like to simply WD it and just use a rag. I love the aged and "rustic" look, especial if you make new top for it. Let the age, use, and abuse show.
