- •Minimal shrinkage compared to art putties.

Cons
- •Sets very quickly, posing challenges for less experienced users to achieve a smooth finish.
- •Requires multiple coats and additional sanding to reach desired results.
- •Confusing product labeling, implying both 'single component' and 'twart component.'
- •Lacks clear instructions, leading to issues with mixing components, especially with the hardener.
- •Users reported inconsistent mix ratio instructions between the product sheet and packaging.

Bottom Line
The Bondo 801 Professional Glazing and Spot Putty is a potent option for professional users looking to refine automotive surfaces, thanks to its strong adhesion and easy sanding. However, it does require a more skilled hand for mixing and applying, due to its fast setting nature and lack of clear instructions. Those new to using putties or seeking a more straightforward application experience might find this product challenging. The use of technical data sheets for precise mixing instructions is highly recommended to avoid common pitfalls.
