Me again – Megan. Could someone give me a “quick” answer – what is the difference in price of 3/8" and 1/2" Plywood? Also, has anyone put on/or seen GAF Prestique 30 BARKWOOD? From the sample that I was given, it looks like a Dark Brown w/Tan… but pictures of it on the Internet on a House looked Brownish-Orange (I am trying to stay away from the Orange). Would Barkwood look good on a Creme Siding?
