Hi, I have got a Focus 5 door and wanted to know of a good sound deadening for the doors. i have tried some different sort of deadening but the doors
still vibrate and is annoying. Does anyone know of a good but not expensive sound deadening.
Thank You.

In the '60s we would buy carpet under felt, cut to size and stuck to the inner door skin with sticky glue. Them days removing the door trim was a two minute job.
