Best product for rotten wood repair?
I have a variety of rotten wood to deal with, some of it is in diagonal tung and groove cedar wood siding and some in PT 2x6 for a deck. Years ago watching a episode of "This Old House" or similar they were dealing with rotten wood around a window. They injected the wood with a hardener. That when dried was able to be painted and they were done and on their way to next project. I am now looking for that quick fix! After doing some research on this site I see MINWAX HIGH PERFORMANCE WOOD HARDNER" mentioned several times. Is that the best product to use? Can it be injected into the soft areas? I would like to do as little as possible to the tongue in groove cedar due to the way it was installed an the texture, to keep it looking original. I have tried using some wood fillers in other areas and it came out really ugly. But then again I didn't really try that hard but that is another subject. TIA!
