I used the search function, but did not see any posts from people that have experience with this product.  I have a Craftsman style house to do, with stained cedar shingles and painted trim.  I have quotes from suppliers for primed and painted cedar, but alternate quotes (with savings) for primed and painted Clear Lam.  It is made as LVL or plywood, but with marine grade adhesives, an MDO facing, and edges are coated with exterior grade elastomeric materials that mask and smooth all the grain.  I want to hear from people that have used this stuff.
