Engine sound insulation

The engine is quite loud. So I decide to put some sound dampening material around it. This needs to be material that is specifically for use in hot environments such as engines. The dampening material is on one side covered with metal foil. The other side has some adhesive, so it can be attached to a surface.

Therefore, the first action was to extensively clean all the metal surfaces around the vehicle engine.

Looks quite shiny after the cleaning!

Now the dampening material can be attached:
