Buying Guide: Key Considerations For Choosing Car Body Putty
- Damage size and depth: Tiny scratches respond well to small putties; larger dents may require a two-part filler with more build height.
- Surface material: Check whether the filler adheres to metal, fiberglass, aluminum, or wood as applicable to your car.
- Drying and work time: Quick-dry formulas speed up projects but may require faster handling; longer work times allow more precise shaping.
- Finish and sanding: Choose products described as sandable or finishing putties if you plan to prime and paint soon after.
- Two-part vs. ready-to-use: No-mix options are convenient but may offer less control over set time and consistency.
- Compatibility with primer: Ensure the filler is compatible with your primer system to avoid adhesion issues.
