Here is an alternative method to modify the Graphics3D object.
Folloing up on David Park's example:
plt1 = ParametricPlot3D[{Cos[t]Cos[s], Sin[t]Cos[s], Sin[s]},
{s, -Pi/2,
      Pi/2}, {t, 0, 2 Pi}, Axes -> False, Boxed -> False];

Then we use the following replacement rule to modify the Graphics3D
object which has the form:
Graphics3D[{Polygon[{xxxx}],Polygon[{xxx}],...},{graphic directives}]

plt2 = plt1 /. 
    Graphics3D[{p__}, {z__}] -> Graphics3D[Prepend[{p}, EdgeForm[ ]],


This method works fine with  SurfaceOfRevolution plots, where it is
not possible to "add" an addition parameter to the first argument if
you want to suppress ofr modify the color /thickness of mesh lines.
