Location: Lower Mainland BC | If any one needed proof that zinc will keep moss and such from growing on your house roof, tell them to look at this photo. The zinc in the pot-metal CHRYSLER letters has been leached out (a bit) by the somewhat acidic natural rain, leaving the area beneath the letter more or less pristine/devoid on mold and algae/moss.
