Corvette Fiberglass Repair - Plastic Surgery

Pour the hardener into a smaller bottle, and cap it with an applicator tip.

Add a couple drops of hardener to the powder, but don't saturate it completely, as you'll use the applicator tip to pick up a small droplet.

Place the droplet into the crack and let dry.

Alternatively, you can sprinkle the powder directly into the crack or hole to be repaired (as long as it can be laid horizontally, so the powder doesn't fall out).

Saturate the powder thoroughly. You don't need to measure the ratio; just make sure it's wetted completely.

Allow the mixture to dry, checking by touch after 15 minutes or so.

Remove the tape from the outer surface of the part.

Use a Dremel or other fine grinder to create a groove in the surface. The following steps also apply to repairing crazing or surface cracks on fiberglass.

Apply powder (or wet droplets) to the groove in the outer surface.

Make sure the powder is completely saturated with hardener.

Use a spreader to force the mixture into the groove and even out the surface.

After the mixture dries, sand the surface evenly until smooth, and then prep for paint.
