Final Thoughts

The Pro Check-Fill Technique:
- Clean thoroughly with solvent
- Sand lightly to create micro-texture
- Apply primer if needed

Pro Fix:
Match filler specifically to the substrate—use metal adhesives/primers for metal, alkyd or acrylic fillers for wood. Confirm compatibility with product manuals.
