Noise deadening and acoustic insulation of the scuttle results in the biggest cab noise reduction.
For those interested in sound deadening the scuttle I used 2mm Silent Coat with 30mm Silent Coat Noise Buffler 30 applied on top.
Although not a big area it‘s unlikely to be found clean and best done with card templates to avoid wastage.
One 1m x 1m Noise Buffler sheet is enough with a small amount left over. All faces were covered inc’ the drivers side (RH) blanking plate for ventilation.
The only places not covered are the passenger side ventilation intake and the scuttle drain ports left and right. When you fit the wiper mechanism back you may need to trim the foam slightly, I left mine as it is only just touching in one place.
It has made a significant difference to the cab noise level, well worth doing.
