## Overview

J-B Weld 32329 Ultimate Black RTV Silicone Gasket Maker & Sealant is a professional-grade, room temperature vulcanizing silicone designed for automotive applications requiring superior oil resistance and heat tolerance. It cures to form a durable, waterproof, sensor-safe gasket that withstands temperatures up to 500°F, making it the go-to sealant for oil pans, valve covers, and transmission components.

## Description

From the manufacturer J-B Weld Silicone Sealant & Adhesive J-B Weld Ultimate Black Silicone Gasket Maker & Sealant is an RTV (Room Temperature Vulcanized) Silicone gasketing material designed for use in mechanical assemblies where maximum petroleum and oil resistance is required. Upon curing, which occurs when the product is exposed to the moisture in the air, the silicone forms a tough, waterproof, gasket and seal on most surfaces. It will not shrink, resists oil and petroleum products, resists weathering, is sensor safe, has good temperature resistance up to 500° F intermittent, and is great for many automotive applications.

Review: Works great - At first i used it with the nozzle but its hard to squish it out so I had to cut it from the second circle to make the hole bigger which worked, please do not force it through the smallest hole since Ive seen some comments complaining that it bursted open and made a mess. I would recommend you remove the nozzle when you are almost done and clean it properly by passing tissue through it, using some of that product leftover. While this might be messy and a bit wasteful it will prevent both the tube and the nozzle from drying up since the nozzle doesnt have a seal. Now i use it without without nozzle and it still works nice for areas that dont require precise application or tight areas and its an amazing adhesive, it says it dries in 1h but id recommend leaving it at least half a day, do the work at night and leave it overnight maybe. Ive used it to glue some shelfs in the kitchen and put spices and sauces which can be quite heavy, left milk and other heavy items to test the durability and its been 3 weeks holding all that weight, also used the glue to seal corners in the bathroom and its completely waterproof once dry. The next time u open the tube there will be a dried up crust on the top, if u squeeze a bit it should come out, i didnt throw it away and actually placed it back once im done using the product and this actually works as a second seal that prevents another dry crust. Overall amazing product.
