Painting wood with green slime
I replaced some wood on a camping trailer last year. I never got it
painted. It's been under a tree all year. Now this new wood has a
green slime or green (something) on it. [What is it?].
Do I need to sand this all off the wood, or can I just scrub it with
bleach, or can I paint right over it? I plan to use an oil based
paint.
