    Directions for using Dynatron Polyester Fiberglass Resin:

    1. Clean the surface with a quality wax and grease remover or acetone to remove any contaminants such as wax, oil, grease, silicone, etc. Let surface dry.
    2. Sand surface with 36- or 80-grit sandpaper down to the bare metal, wood, or fiberglass surface for maximum adhesion.
    3. For one half of the resin container (2 quarts), use one tube of the liquid hardener (22mL) supplied. Or use one quart of the resin to one tube (11 mL) of the liquid hardener. For smaller amounts, add 10 drops of liquid hardener to 1 ounce of resin. Mix thoroughly for about 1-2 minutes.
    4. Apply a coat of the mixed resin to the damaged area. Lay a piece of fiberglass cloth or mat over the damaged area. Immediately apply more of the mixed resin to soak the cloth or mat. If additional coats are required, apply immediately while last coat is still sticky/tacky or wait 2 hours and sand with 80-grit sandpaper before continuing application. Allow 1-1/2 to 2 hours to cure before sanding.
    5. Sand with 80-grit sandpaper and use 220-grit sandpaper to featheredge. If a smoother edge is needed to fill a low area, apply Dynalite™ Body Filler and follow the directions for finishing.
    6. Prime and paint the finished repair area with primer or paint.

    IMPORTANT!

    DO NOT USE RESIN BY ITSELF WITHOUT FIBERGLASS CLOTH/MAT. DO NOT PUT MIXED/UNUSED MATERIAL BACK INTO CONTAINER AS IT WILL HARDEN THE ENTIRE CONTENTS.
