During repairs, which of the following is essential to achieve a good bond in fiberglass?

Thorough cleaning of the repair area is essential to achieve a good bond in fiberglass because any contaminants such as dirt, oil, dust, or old resin can compromise the integrity of the bond between the fiberglass layers. A clean surface ensures that the adhesive or resin can properly penetrate and adhere to the fiberglass materials. This is crucial in creating a strong and durable repair, as the effectiveness of the bonding process heavily relies on surface preparation.

Effective bonding in fiberglass repairs often requires not just cleaning but also proper surface treatment, such as sanding, to increase the surface area and enhance adhesion. Ensuring that the area is free from contaminants contributes significantly to the overall success of the repair, making it an indispensable part of the procedure.
