Can You Bondo Over POR 15? Navigating Compatibility Challenges

1. Compatibility Factors:

Achieving a successful bond between Bondo and POR 15 depends on several factors, with meticulous surface preparation, proper application techniques, and precise timing taking center stage.

2. Surface Preparation: The Foundation of Success

Before contemplating the application of Bondo over POR 15, meticulous surface preparation is imperative. Cleaning the POR 15-coated surface thoroughly, removing any dust, grease, or debris, sets the stage for a strong bond between the coatings.

3. Timing Is Crucial: Finding the Sweet Spot

Timing plays a critical role in the compatibility of Bondo and POR 15. The POR 15 surface should be dry, fully cured, yet still possess a slight “tooth” for optimal adhesion. Applying Bondo too soon or too late can compromise the overall bond.

4. Choosing the Right Bondo Formula:

Selecting the appropriate Bondo variant is vital for a successful integration with POR 15. Opt for a formula explicitly designed for use on metal surfaces and tailored for automotive applications.

Step-by-Step Guide: Applying Bondo Over POR 15

1. Clean the POR 15 Surface:

Thoroughly cleaning the POR 15-coated area is the first step in the process. Remove any contaminants that might hinder the bond between POR 15 and Bondo.

2. Surface Roughening: Enhancing Adhesion

Gently roughening the POR 15 surface with fine-grit sandpaper enhances adhesion. This slight texturing provides a better surface for the Bondo to grip onto, ensuring a robust and enduring bond.

3. Apply Bondo with Precision:

Using a spatula or applicator, apply Bondo over the prepared POR 15 surface. Precision is key here. Ensure an even application, smoothing out the compound for a flawless finish.

4. Sanding and Shaping: Crafting Perfection

Once the Bondo has cured, delicately sand the repaired area to achieve the desired contour. Patience is paramount during this step to prevent over-sanding and compromising the integrity of the bond.

Common Pitfalls and How to Safeguard Your Restoration

1. Rushed Application: Take Your Time

Rushing the application process by applying Bondo over uncured POR 15 or hurrying through the steps can lead to adhesion failure. Patience is indeed a virtue in the realm of automotive restoration.

2. Insufficient Surface Preparation: Attention to Detail Matters

Neglecting thorough surface cleaning and roughening compromises the bond between POR 15 and Bondo. Dedicate time to meticulous preparation for optimal results.
