Anti Sieze

[RobinW]

I have a tube of copper paste that I've been using and a can of silver based which I haven't been using as I read someplace that it turns to something like concrete over time.

 

It that a crock?

 

The copper is getting a little low and I do have a can full of silver.

Silver to Aluminum has a higher corrosion potential than Copper to Aluminum so it is more likely to form corrosion or seizing in a BMW engine application. Buy a tube of anti-seize designed for use with aluminum. You know it will last for years.
