Read it many times. Where it has some good info ,in most cases about as vague as talking directly to James Hardi. In talking to JH, they would not committ to what "Moderate Contact" is. I thought people who had hands on experiance with the product would know better than anyone. I am probably over analyzing this thing but living on the Fl coast and working for the power company and seeing first hand from Miami to North Fl on the east and west coast what wind drivin rain as well as full blown hurricanes can do to I want to be sure I get it right.
