Tetramethylbenzidine (TMB) staining

We're using TMB to stain cells labeled with antibody-HRP.  The
signal/noise ratio is great, but we're having a problem mounting our
specimens.  They all seem to cause rapid fading:  glycerol, nail polish,
DPX (Aldrich), TBS's Tissue Freezing Medium, Permount, TissueTek's OCT.
Any ideas? Most of them seem to be poly-ols, maybe that's a problem.
Maybe a silicon-based mountant?  TIA.
