I have been doing IHC in GMA with lots of success. 
Our lab uses Polysciences Immuno-bed kit which is a
GMA based plastic but is specially formulated to be
used in light microscopy immunohistochem procedures. 
I then adapt my paraffin IHC protocol to longer
(usually double) incubation times at 37 degrees
instead of room temp.  However, if the paraffin
protocol calls for a primary antibody incubation of
overnight at 4 degrees I would keep it at that.
