I’ve taken a few days of work with a plan to start painting the house. This plan has fallen flat on its face as the weather isn’t playing ball. We had snow down to 700m yesterday, it’s cold, went and windy. So I retreated to the warmth and comfort of the garage.
I still have an acre of Dynamat leftover and I’d been toying with the idea of sound proofing the underside of the bonnet. Lets do that then 🙂
Spare wheel and the 4 rubber feet are removed. I’ve also removed the sun shade for a number of reasons…1. It creates a lot of wind noise and 2. I can’t see the traffic lights easily if I’m at the front of the queue! It also serious effects the “barn door” drag coefficient of the vehicle… cant be having that!
Ready for some sound insulation.
A whole unopened box of Dynamat 🙂
I was able to cover the 3 middle panels with some offcuts. I deliberately left a small gap around the edges of the Dynamat. This will be covered with some Dynamat trim tape… which I don’t have right now.
I can’t remove the bonnet easily on my own, so with a piece of pipe lagging on the drivers wiper blade and a length of rope from the bonnet to the spare wheel on the rear door, I can hold the bonnet up vertically. It makes things a lot easier.
I made some cardboard templates for the 2 larger areas. This stuff is incredibly sticky and once it’s on… it’s on.
Bonnet strut reattached
… and then the sun came out… Spare wheel back on. I quite like LGL without the sun shield.
Hi Oliver, thanks for leaving a message. From the bonnet alone, there was a little reduction of noise from the engine bay…. but not a lot.
The Dynamat on the doors, floors, bulkhead, seat box, rear tub and roof does make a difference and reduces transmission and road noise but I had the advantage of doing this work when the car was in pieces.
I particularly noticed the deadening effect recently whilst cycling through the gears with the transfer box in neutral and the cubby box and tray removed. When I put the tool tray back in (also lined with Dynamat) the noise reduction was striking.
If you’re looking for a noise reduction product, I can highly recommend the Wright Off-road front mat system. Exmoor trim also sells them. I’ve had one before and it was excellent.
Hope this helps.
Kind regards
Andy.

Is there a notable difference after sound proofing?
