2. Odor: The sealant has a strong odor, which some users may find unpleasant. However, this is common with many silicone-based products and typically dissipates over time.

3. Tooling: Applying the sealant requires a caulking gun, and it can be messy, especially for those who are not experienced with using such tools.

4. Premature Curing: If the sealant is exposed to moisture before it has had a chance to cure, it may start to cure prematurely, affecting its overall performance.

Conclusion:

Its ability to withstand extreme temperatures and resist water, moisture, and UV rays makes it an excellent choice for outdoor use.

Recommendation:

If you're looking for a reliable, weather-resistant sealant for outdoor projects, Permatex 81158KK could be a good choice.
