## Overview

Permatex 81173 Black Silicone Adhesive Sealant is a high-viscosity, sensor-safe RTV sealant designed for indoor and outdoor use. It bonds and repairs multiple surfaces including glass, metal, and vinyl, offering waterproof, vibration-resistant protection across a wide temperature range (-75°F to 450°F). Ideal for automotive, electrical, and general maintenance, it dries to a flexible, peelable rubber seal that endures extreme weather and temperature fluctuations.

## Description

Permatex Black Silicone Adhesive Sealant is a general-purpose, black RTV indoor/outdoor sealant. Effectively bonds, repairs, seals, mends and secures glass, metal, plastics, fabric, vinyl, weather stripping and vinyl tops. Also protects and repairs electrical wiring and may be applied to horizontal or vertical surfaces. Waterproof and flexible with a temperature range of -75 degrees Fahrenheit to 450 degrees Fahrenheit, this sealant is oil, water, weather, vibration and grease resistant. Suggested applications include windshields, door frames, electrical connections, seams and roofs, vinyl tops, and weather stripping.

Review: Excellent Product - I had a leaky sunroof (it's not draining properly and cleaning the channels repeatedly has done nothing) on my truck and have tried quite a few products already. But none of them could hold up to the Florida heat and weather, and would end up deteriorating and crumbling. I tried this product on the seal around the window and have had no leaking whatsoever. This stuff comes out like a thick black, tar-like caulking and is NOT easily cleaned from the hands or anything else you get it on, so be careful. You'll need gas or WD-40 (or something similar) to remove this stuff. Or just wear gloves, if you're messy like me. When it dries, though, it turns into a thick rubber-like seal that has elasticity and works extremely well; it is still holding up with no problems at all. Another bonus is that because it's a silicone seal, you can easily "peel" this stuff off if you ever want to remove it. Just pry up a part of the coating, and it'll all peel away in a big strip. And when I purchased this, it came as the product that is shown (with nozzle). There are also tubes of this product available, which I've used since and had no problems applying it.
Review: Worth the buy - Why did you pick this product vs others?: Great sealant quick dry time. Durability: Very well seal
