Get the blocking wrong and the consequences follow later: an opening sash that drops out of square, a stress crack running from an edge, or a bead that will not sit down. Most of these are re-glazing errors rather than product failures.
Beads themselves are handed and sized. Reusing the wrong bead, or refitting one stretched during removal, leaves a gap that lets water sit exactly where it should not.
