Product Summary

JB Weld Black Silicone and Sealant Adhesive is a general purpose RTV (Room Temperature Vulcanized) silicone. It is designed for sealing and bonding uneven surfaces. Upon curing, which occurs when the product is exposed to the moisture in the air, the silicone forms a tough, waterproof seal on most surfaces. It will not shrink or crack, resists weathering and is great for many automotive accessories and household applications.

    1 answer

    1. While JB Weld Black Silicone and Sealant Adhesive can technically be used to re-glue a rearview mirror to a windshield, it's not the ideal choice as it's not specifically formulated for this application. It would be recommend to use a dedicated "mirror adhesive" which is designed to bond mirrors to glass surfaces with high strength and durability.

    1. It is not recommended to use the black silicone and sealant on a car tire. Securing the sidewall with an adhesive is not safe and can lead to tire failure. If the side wall of the tire is damaged, it is recommended to replace the tire completely.
