We have an older Victorian house we are restoring and are currently working on our front porch. We'd like to replace the current decking which we believe may be called "car siding". It is only about five years old but is warping and has already begun rotting despite a good painting. Is there a good grade of tongue and groove material you would recommend that would be durable and attractive. We'd like to avoid the "modern" look achieved with treated bull nose deck wood used so often in backyard decks.
