Review: Just get this. Don’t mess about with the cheap rubbish - Don’t waste your money on any other adhesive sealant as this is clearly the best. I use it for so many things and i wouldn’t start any job without having a couple of tubes of this to hand. Les Halsall

### ⭐⭐⭐⭐⭐ This is the stuff you're looking for...
*by B***T on 9 August 2023*

Seals and sticks well, just ensure you have a robust sealant gun as it's thick stuff! Not as easy to finish as silicone or caulk however it provides a much better result.
