GLYX is a white filler for repairing holes, cracks or scratches in fibreglass. Sets in 10 minutes.
DIRECTIONS FOR USE: Can be combined with "REXIM FIBREGLASS" for larger repairs. After sanding REXIM FIBREGLASS, add hardener to the "GLYX CELCOAT FILLER" and stir thoroughly; then go on to sanding smooth (smooth plaster) surface to fill any surface irregularities. After about 10/20 minutes, go on to sand down surface with a 120 grade sandpaper, then with a 260/280 water abrasive paper; finally, refine with a 400/500 water abrasive paper. Now you can polish the surface in order to obtain a perfect and invisible repair.
