YELLOW FILM MARKER

GT075 YELLOW FILM MARKER 
1) Marking film prior to installation of windows with unusual shapes (arches, trapezoids, etc.) which must be cut to approximate shape before the final “lay- up”.
2) Circling a contaminant (hair or fiber) before pulling back the film to remove it.
3) Marking film edges to check for glass movement on side roll-ups during the trimming process. Yellow grease mark easily wipes away.
