### **Cons**

1. **Potential Messiness** Large containers can be cumbersome to handle, and spills or overapplication may occur, especially if not properly contained during use.

2. **Drying/Setting Time** Some sealants require significant drying time before surfaces can be used or repainted. This could delay projects if not accounted for.

3. **Limited Flexibility in Some Cases** While designed to be flexible, some waterproof sealants may crack or peel if subjected to extreme temperature fluctuations or physical stress over time.

4. **Chemical Sensitivity** The product may require surface preparation (cleaning, priming) to ensure proper adhesion. Improper prep could lead to poor bonding or failure.

5. **Environmental and Health Considerations** Like many industrial sealants, this product may contain solvents or chemicals that require proper ventilation and disposal. Always check for VOC content and safety data sheets (SDS).

6. **Brand Reliability** NYBQ is a lesser-known brand compared to established names like 3M, Permatex, or Loctite. Quality and consistency may vary, so research or reviews from users with similar applications are advisable.

7. **Application Skill Required** Achieving a professional, invisible finish requires practice. Overapplication or uneven spreading can leave visible lines or bubbles.
