Answer:

The best way to make it look professional is to make the surface flat with a sharp tool and after to polish with a 400 or 500 revolutions motor tool. If you add any resins will be not nice at all. Better go to a professional to do this, they use very special tools you'll pay some money but the result will be good, but if they will use resins, run away from there!!!
Call the Fire Department. It's free if you're in the U.S.
well the most dangerous of gases usually are odorless so unless its flammable. Get a detector because they are all around useful. I would continue to call until they pick up because something like that should be looked at.
