I took the be creative option rather than paying £15 to buy a foam thing, so i got a square of the plastic used to cover the mushroom houses:

I sat the doorcard over the plastic and drew a line around it, i work on the principple that its easier to take away than to add so dont worry if its too big originally:

Here was the thing cut out:

I like putting a date and signature on my work:

Get it on over the door and use a bit of duck tape to do a bit of trimming to get it just right:


Then i took the thing off, and put on the sealant where the protector will come in contact with the door, a good thick bead means a good seal:

Then i put the doorcard over it, noticed that in the left bottom corner a bit of foam needs a hole, so i cut it out and put the door card back on, with a protector like this one, give the clips a good firm bang on, its popping through the plastic for the first time.
Thats it
As for rattles and crackles of using plastic because this stuff is thick it doesnt sound like a shopping bag and if it did my car is equipped with a thing that universally deadens noises its called a JBL amplifier connected to a cd player with status quo in it.
