Put on a respirator. Inhaling clear coat remover can irritate the linings of the nose and throat.

Apply clear coat remover to the surface of the fiberglass with a paint brush. Clear coat remover requires time to chemically react with and dissolve the clear coat. Refer to manufacturer instructions for reaction time. During the reaction, the clear coat will bubble and pull away from the fiberglass.

Spray the clear coat remover from the surface of the fiberglass with a spray hose.

Wipe away any excess dissolved clear coat with a clean towel.

Reapply the clear coat remover, allow it to react with any remaining clear coat, and spray away the residue.

Wipe away any excess dissolved clear coat with a clean towel.

Prepare the area to be repaired. Remove any debris or flaking. Chip or cut the surface so that the product can fill in and adhere. For example, if you have a crack, cut or grind a groove down the middle so the jelly can get into it and stick. Measure the size of the fiberglass cloth you will need to cover the area if you are using it in the repair. Cut it now to have it ready.

Wear the gloves and safety goggles, and clean the surface of the repair area well with acetone and a clean cloth.

Pour the amount of fiberglass jelly you estimate you will need for the first application into a clean disposable cup. The jelly hardens fast, so time is of the essence, and you dont want to waste product you cannot use.

Spread a layer of the jelly with a brush or flat paddle-type stick. Work it into the groove or hole, wherever the product needs to fill. Work the layer of fiberglass cloth into the jelly layer if you are using cloth to reinforce the repair. Apply a thin coat of the jelly over top of the cloth, like a reverse sandwich.

Allow to dry completely. Fiberglass jelly dries quickly. Depending on the temperature and humidity, the area could be ready to sand within 20 minutes. Sand with heavy grit sandpaper and smooth out the repair.

Apply another coat of jelly or jelly and cloth, if necessary. The cloth should be embedded enough not to come through during sanding; it can be used minimally with the jelly. Dry and sand as before. Feather the edges of the repair until the area looks like the rest of the surface.

Clean the area with acetone. It is ready to paint.
