Why PaintSource chooses Abatron vs Bondo


Abatron would be considered superior to Bondo for most architectural applications. The following discussion summarizes my thoughts.

Purpose & Applications:

      • Abatron: Primarily formulated for wood repair and restoration. Abatron’s products, like WoodEpox, have been effectively used to rebuild and restore wood details on historic structures, like old trim, entry doors, or very old exterior columns. These products restore and stabilize damaged wood sections.

      • Bondo: Initially intended for automotive body repairs, it’s often used as a wood filler, but might not be the best for extensive exterior work due to shrinkage and hardness issues.

        1. Flexibility & Strength:
              • Abatron: Mimics wood properties, providing a durable repair that can move with the wood. The discussion mentions the product’s capacity to harden rotted wood, making it exceptionally sturdy.

              • Bondo: Being rigid, Bondo might not match wood’s flexibility, leading to potential issues over time.

          1. Adhesion:
                • Abatron: Known for securely bonding with wood, ensuring a long-lasting repair. The Abatron system, as mentioned, allows for repairs that are incredibly solid, even in challenging areas like tenons or rotted joints.

                • Bondo: Its bond might not be as resilient, especially when used in large exterior areas.

            1. Durability & Longevity:
                  • Abatron: Highly resistant to moisture, making it perfect for outdoor wood repairs. Users have testified to its long-lasting results, even suggesting that repairs could be better than the original.

                  • Bondo: Might not have similar resistance to moisture and can shrink over time.

              1. Ease of Use:

                    • Abatron: Easy to mold, cut, tool, and sand, although it’s noted that it sands hard. You can shape it, drill into it, or even route it, allowing for detailed repairs like recutting mortises.

                    • Bondo: Requires experience to achieve a seamless finish.

              In conclusion, while both Abatron and Bondo have their places, Abatron stands out for wood repair and restoration due to its superior bonding, flexibility, and durability, especially in challenging or historic repairs. Bondo, primarily for automotive repairs, might not offer the same long-term results as Abatron for wood.

              Most users have expressed satisfaction with Abatron, especially for its hardening capabilities. Using the consolidator can make rotted wood exceptionally solid. Many users have expressed that after repairing rot or damage, they believed the repairs might be better than when the wood was new.

              Bondo and other similar fillers have been criticized for their limitations in extensive exterior work, with issues like shrinkage and extreme hardness, ease of sanding, and difficulty blending to surrounding wood.

              Real-world testimonies from our clients further bolster Abatron’s standing in our comparison.
