Titebond43991 Weather Master Sealant Cartridge, 10.1 oz., Crystal Clear

Good adhesion to multiple materials. A bit pricey though. All in all it seems to adhere to materials other caulking compounds don't. No idea as to how long it will last under normal weather conditions, but I am hopeful it will repair a leaky solar panel. I will update if there is a problem.

Excellent sealing and adhesive plus the clear looks better than white!

This is the best weather sealant out there. Incredibly durable.

This sealant was worthless. The tube was at room temperature when I loaded into the gun and punctured the foil. Despite heavy pressure, only a small amount of sealant came out. In desperation, I cut open the tube and found the sealant to be almost solid. I paid a premium price for this sealant and was very disappointed.

Did the job.

I used this to wrap up the last of my caulk jobs late in the year in very cold weather, and it works great. Normal silicone would have failed.

The Titebond Crystal Clear sealant was like a tube of hard rubber. I was not able to use it and just threw it away. Purchased a tube of GE clear caulking from Lowe's. It worked great!

Did not work as well as described.
