Benjamin Obdyke sells a product called Home Slicker, to be used between Tyvek and Siding. The idea apparently is to eliminate the need for furring strips, and provide an air gap for drying puposes. Has anybody used this product? What did you think? My local builders supply had never heard of it, but they did a little research for me and told me they could get it. Anyway I thought some of you might be interested. Google - Benjamin Obdyke.
