So today I have mostly been fitting a spot of sound deadening. Whilst I am happy that the car is a diesel, I have to say I don't overly love the sound of Diesel engines. From the factory the ST comes with some decent sound deadening in the form of the engine cover and bonnet lining. However I decided I would try and improve it slightly. Bought some mating here:

Came very quickly so got busy today. Here's the bonnet with the thick liner in place as from the factory.



This is what it's like underneath:



Three definite areas that can be hit with some deadening.

First thing I wanted to do was ensure the surface area was completely clean so gave it a wipe down with this:



Method I used was to make stencils with cardboard by taping the cardboard over the area and pressing it in with a screwdriver in order to form the shape. First stencil done and drawn onto mating.



First bit cut and in place.



Second one on.



Time to stencil the middle section



Cut and in place to finish it off.



All finished and original liner back on to cover it over.



It has definitely softened the noise inside, although I think doing the bulkhead would improve this more. This is just one part of the sound deadening I plan on doing.
