Anybody ever use this stuff?  It is basically an exterior plywood, with an MDO type facing, and the same stuff is used to wrap the edges.  It is sold in 1×4 and 5/4 in nominal widths from 4 up to 12, and comes in 16 foot lengths.

I am thinking about it for trim on an all-painted job, but have some concern about ripped edges and the look of nail holes when puttied.
