Review: Functions good, one time use - I used this adhesive after deliding a CPU. I was able to easily cut/form the supplied nozzle to the right hole size. The glueing application went smoothly. I doubt that I will be able to use the tube and nozzle.
Review: Best for BMW valve cover - This product worked great on my plastic valve cover fix. I used hard setting epoxy first but over couple months it cracked with valve cover for BMW. This stuff stays adhered and flexible. This is the only product anyone should ever use for BMW valve covers

### ⭐⭐⭐⭐⭐ Functions good, one time use

### ⭐⭐⭐⭐⭐ Best for BMW valve cover
*by P***R on March 27, 2019*

This product worked great on my plastic valve cover fix. I used hard setting epoxy first but over couple months it cracked with valve cover for BMW. This stuff stays adhered and flexible. This is the only product anyone should ever use for BMW valve covers

### ⭐⭐⭐⭐ Better bulk than Permatex
*by G***Y on January 23, 2022*

While a 572 degree F sealant is not needed for most parts of an internal combustion engine, this sealant does give you a peace of mind around the heads or exhaust. It has better bulk than Permatex, so will fill larger gaps. I would not use this product as gasket prep, as it is too thick, and does not skim well.
