My husband and I would like to get back the "natural" look of our cedar siding. Right now our house is brick red. The house used to be the horrid olive green color. The green paint is under the red. Any suggestions? We have talked about sandblasting, but I haven't researched it to see if it is even feasible. We would rather not go to the expense of hiring someone to do this for us. Any advice for the do-it-yourselfers would be greatly appreciated!!
