I have a 98 Civic and the rear window defroster has a couple of
"stripes" that don't work. It looks like they've been scratched in a few
places.

Has anyone successfully repaired something like that? I was looking at a
product called "Frost Fighter" which is basically a conductive glue that
you apply over the breaks.

I called Honda and they said they would have to replace the whole rear
window, which seems a little excessive.

Here's the link for Frost Fighter:
