## Description

J-B Weld High Heat Epoxy Syringe, Dark Grey

Review: Easy to mix - Worked well for my application. Needed a solution to cover up oem exhaust baffles for a 2021 Chevy Trailboss. This was easy to mix and apply with a small boars bristle brush. Went on at the right consistency and seems to be holding up well.
Review: J-B Weld High Heat Syringe, Dark Grey - This stuff is awesome. I recently discovered J-B Weld. I'm a 60 ish year old woman who knows just enough to be dangerous when it comes to diy repairs. I used it to seal a crack in my concrete furnace pad. I taped off the concrete surrounding the crack and used a throw away sponge brush to fill the crack and smooth out. I then removed the tape and it looks like a professional job. Was quite pleased. Wish I would have known about this product sooner. Also, mixing the product is extremely easy with the provided plungers that squirt the exact amounts of liquids simultaneously.
