anti-betagalactosidase in paraffin slides

Has anyone had success with antibodies against B Gal in paraffin embedded tissue?  We have tried several with no success and ICN does not recomment the Cappel rabbit ab in paraffin.  I cannot use frozen sections (am working with embryonic-early post-natal mouse inner ear and need sharp morphology.  Is there hope?  Thanks in advance for any assistance.
