Here in GA we're seeing many oaks with signs of a disease with the main symptom being patches of smooth grey bark when the bark normally has fissures and is more "3-D". Red Oaks are the most commonly affected. Anyone have an idea about what this is ?

I'll try to get some pictures this week if possible.

Good idea. In the meantime, search Aleurodiscus.

PS it may not be a disease at all. Scratch the smooth part and look within.
 
"Sounds like Hypoxylon Canker"

Hypoxylon is sometimes tan sometimes gray but usually black.

Way too little info to be imagining fatal conditions imo.
