Done a bit of sound deadening last week,a trip to the scrap yard,picked up three under the hood sound deadening mats the cleanest i could find £5.
First job engine bay,using thin cardboard as a tem/plate i cut out the shapes on the existing sound deadening material on the inner bulk head,then cut out the pieces from one of the mats,using spray on glue i've doubled the thickness of the sound deadening,next over the wheel arches including under the air box.
Inside the cabin,passenger and drivers footwell,right under dash it was bare metal on mine,cut to shape and glued on,making sure the hot air outlet was'nt obstructed,and all three pedals could be depressed.
Next,under the back seat using one of the mats cut to fit no glue the seat holds it in place.
In the boot,removed the plastic trim from around the wheel arches cut to fit on the bare metal then glued on,at the same time i cut out a piece of thick foam back carpet i had in the garage and put it under the boot carpet then replaced all the trim.
The back door,took off the plastic covering and with my last mat,i cut to shape on the metal side and glued on i was going to do all four doors but i ran out of material,plus there was the electrics to consider.a job for the future perhaps!!
Did it work,...sort of,...at tickover and low speed there's an inprovment,at a higher speed..the jury's still out
