Fiberglass Crack and Puncture Repair

Fiberglass repair rebuilds cracked and punctured laminate by grinding back to sound material, laying new glass and resin in a tapered scarf, then fairing and refinishing. The repair restores the panel's structural continuity rather than only its appearance.

Symptoms

Signs you need this work

Visible crack radiating from a corner or a fastener
Puncture or hole from impact
Spider cracking in the gelcoat
Previous repair telegraphing back through the paint

Laminate, do not fill

The correct repair grinds the damaged area back to sound laminate in a tapered scarf, which gives the new material enough bonded area to carry load across the joint. New glass and resin are laid up in stages, then faired and refinished.

Filling a crack with body filler bridges the gap without restoring any strength. The panel keeps flexing, the crack keeps moving, and it reappears through the paint within a year.

Fairing to the original contour
Gelcoat or primer and paint refinishing

FAQ

Fiberglass Crack and Puncture Repair questions

Why did my last fiberglass repair crack again?

Almost certainly because it was filled rather than laminated. Filler has no tensile strength across the joint, so the panel keeps flexing at that point and the crack returns.

Can you repair spider cracking?

Yes. Spider cracking is usually gelcoat rather than structural, and it is addressed by removing the affected gelcoat and refinishing. If it is a symptom of flex, the underlying stiffness has to be addressed too.

Do you repair from behind the panel?

Where access allows, yes, and it makes a stronger repair. Where the back is not accessible we build the strength into the scarfed laminate from the front.
