Thanks for the advice.
I just had a lingering concern about the OSB sheating and its ability to hold a nail. It has not been tested for Cedar Shake applications ( as per the Cedar Shake and Shingle Bureau.) They only tested Plywood. It should be OK with OSB as it is widely used for Shakes as far...

I recently saw an application of a marine epoxy coating to strengthen a historic brick wall. That was in Europe.
I'm tempted to use this technique on a cedar shake roof. The roof is built of 1/2" OSB sheating with No:1 heavy shakes installed over the sheating using 2" No. 6 shake...
