I also think grinding would be very tedious. I have used zylene before when removing tuff glues and sticky residues. It stinks worse than your grey fuzzy stuff and is hazardous. So wear a protective mask

Since I don't know, I asked Mike at Wildfire about coatings. He suggested using a few coats of Duratec high build primer and then paint it with a brush/roller. It won't be mirror smooth but I think a clean orange peel effect would look good. Click here for

Good Luck and don't forget to shave off those "Forehead Spikes" hanging down from the skylight
