Sound deadening a 306

[Just Sean]

I used a mixture of 9 and 11mm underlay in mine. Paid 35quid for a full roll of the 9mm and half a roll of 11mm.
Plus 2x tins of contact adhesive. I Put some underneath the bonnet, between the bonnet and the cover thats their already. The back of the seats (in a 5 door) have zips at the base of them, so i put some behind the seats too.

had about a quarter of 9mm left and sold it to a work colleague for £20quid!

So impressed with the results and only took a day!
