Now let's kick it to Chat GPT to see what it has to say on the differences between the two...

"Bondo Plastic Metal and spot putty are both automotive repair products used to fill and smooth imperfections in vehicle surfaces, but they serve different purposes and are applied in different stages of the repair process.

  1. Bondo Plastic Metal:

  • Purpose: Bondo Plastic Metal is a type of body filler designed for more substantial repairs. It is ideal for filling dents, rust holes, and other larger imperfections in metal surfaces.

  • Composition: It typically contains a mixture of polyester resin and metal particles, making it durable and suitable for repairing metal surfaces.

  • Application: Bondo Plastic Metal is applied over the damaged area, where it adheres well to metal surfaces and provides a strong, sturdy base for further refinishing.

  1. Spot Putty:

  • Purpose: Spot putty, on the other hand, is a finishing product used for smaller imperfections, pinholes, scratches, or minor dings in the bodywork. It is not intended for large or structural repairs.

  • Composition: Spot putty is usually a fine-grain filler that may contain ingredients like nitrocellulose or other polymers. It is formulated to be smoother and finer than body filler.

  • Application: Spot putty is applied over the sanded and primed surface, filling in tiny imperfections. It is meant to provide a smooth, even surface for painting.

Choosing Between the Two:

  • Use Bondo Plastic Metal for larger repairs where structural integrity is important.

  • Use spot putty for smaller, more cosmetic imperfections, and as a final step before painting.

  • It's common to use both products in sequence during the repair process, starting with Bondo Plastic Metal for major repairs and finishing with spot putty for fine-tuning the surface before painting.

Remember to follow the specific instructions provided by the product manufacturer for proper application, drying times, and sanding techniques to achieve the best results."
