Jack repair wood frame water damage 98 caribou

Just a quick update I used copper green and minwax wood hardener instead of Git-Rot. Its about half the price and a local RV repair told me its how they do the same repairs. I applied copper green today and worked on stripping the lauan of the wing. I will apply second coat of copper green tomorrow and put in the insulation board. Not really much to take pics today but I will tomorrow when much more progress.
