I'll echo the previous commentse: 1) hire a pro, and 2) why are you still alive!? Sometimes, things like this seem like a slapstick comedy skit without the comedy.

Encapsulation is good, paint is probably good, tape is good. Spray-paint, maybe not so much. That the force with which the stuff comes out could conceibably knock something into the air before the paint gloms onto it. Also, metals in spray paint such as cadmium, and solvents, aren't less carciinogenic than asbestos. You'd need a respirator that filters vapors AND particulates.
