maybe consider using a putty knife with a flexible blade (that
can be filed to a sharp edge).

or maybe a flush-cut saw
http://doityourself.com/store/6966105.htm
(it has a flexible blade that lays flat on a surface, and the
teeth are not off-set - meaning it won't scratch the surrounding
area as much as a regular saw blade would)

as for 'finish cleaning', much would depend on what the next step
was?    If you use an electric sander, start with a fine grit
paper (150), be careful, and see what that does to the 5200 -
*and to the surrounding fiberglass* - before going to coarser
grits.  You may find that sanding/grinding removes surrounding
fiberglass  faster than it does the 5200.
