Buying Guide
Key considerations when choosing auto body glazing putty:
- Substrate compatibility: Check whether the putty is formulated for metal, fiberglass, wood, and primed surfaces to match your project.
- Two-part vs. one-part: Two-part formulations typically offer stronger bonding and durability but require mixing. One-part putties are simpler but may have shorter working times.
- Work time and cure indicators: Shorter work times speed up projects but require faster application. Color-change indicators help avoid over-sanding and under-curing.
- Sandability: Faster sanding reduces labor time. Look for formulations that sand smoothly without leaving scratches or gouges.
- Primer readiness: Ensure the putty sands to a surface that accepts primer and paint evenly without pinholes or texture issues.
- Shrinkage and cracking: Some putties are designed to minimize shrinkage; this is crucial for large or high-stress repair areas.
- Storage and handling: Proper hardener ratios, shelf life, and mixing requirements affect long-term usability.
In selecting among these options, consider your substrate, the size of the imperfections, whether you prefer a color-change cure cue, and whether a two-part system aligns with your workflow. For heavy-duty or professional shops, two-part systems like Bondo Professional Glazing Putty can offer robust performance, while color-change putties can simplify curing checks on larger jobs. For quick, minor repairs on varied substrates, the single-component or color-change variants may provide practical benefits without sacrificing finish quality.
