John,

If this helps here is a reference where I employed a
sequential staining protocol due to the need to use
the same section for two stains, the latter being
retrospective of a larger study. Both monoclonal mouse
IgG antibodies were stained sequentially using the
same  section after by stripping off the first HRP/AEC
reaction.  Just think of the tissue as a fragile
membrane.
