zamboni vs straight paraformaldehyde

From:David Van Reyk

happy new year to all,
[I think my firts attempt at posting this inquiry failed]
we have been provided with an immunohistochemical protocol for forzen sections that requires Zamboni's fixative. In our lab we normally use 4% paraformaldehyde. The protocol mentions that zamboni's is used to keep the sections from falling off the slides. Is this the only reason Zamboni's would be used over straight paraformaldehyde or are there other advantages.
