The back side of my garage is shadowed by branches from neighbors trees, which causes mold/mildew to grow on the vinyl siding. Since removing the trees/branches is out of the question, is there some type of product that can be applied to the siding to prevent this growth?
Currently I power wash the siding once a year, but the chore has lost it's fun factor so I'd like to avoid doing it. Even if the product/procedure could reduce my maintenance to every other year or every few years, that would be a significant gain in my book.

Rustoleum sells a mold/mildew-proof paint called Perma-White.
They also sell a fungicide (Tiabendazole) additive called ADD-2 you can mix into your preferred paint.
Either of those should at least help some.
