Narrative:
While working on a B777-200 'C'-check job card; for removal of vertical stab panels; and on previous B777-200 'C'-checks; I found multiple panels installed with shanked out (too long); stripped out; and steel fasteners; instead of titanium fasteners. Also; the sealant covering the panel edges were incorrectly applied. It was excessive and caused damage during removal. This was noticed on numerous panels on entire tail.
