I have lots of holes where insulation can be mounted, but no, just the painted surface.
Am I missing something? No kit listed in the Accessories list, UK or AUS.
Edit: Someone will ask the "Why" question, they always do. Well, I do a battery resting voltage check each Saturday at 11:00 and have this big naked painted surface in my face!
Non on the underside of the bonnet, George.

Beaver are well known for drinking petrol, Andy. It's why they are able to get the wheels spinning.

The million dollar question, was it worth 6hrs labour and £100 of materials? Mmmm, not really.
I used a decibel meter app on my phone before and after, same stretch of road, speed limited to 60mph, stereo/aircon all off. Before on the left, after on the right. It dropped the average by 0.7dB, so not a vast improvement, although as decibels are a logarithmic measure, that's a bigger difference than it seems.
As my phone was mounted in a holder near the windscreen, I think that wind noise is the main factor. Interesting that the minimum level was far lower in the 'after' run, which suggests to me that at low speed (where road noise is a bigger factor), there was a more dramatic improvement.
Overall my perception of noise is that things seem more muted after installation and the stereo seems to be louder at a given volume setting.
So only really a modification for people who enjoy mucking around with their car, rather than an essential upgrade.
