It's a peel and stick type stuff. There are several different brands. This one is called B-quiet. It worked pretty well. I can now here the radio when I drive.
Next up was the padding.
I just bought some stuff from Home Depot. It was pre-cut, 6x9 , I think. You can see where I cut the holes for the screws that hold the chairs down.
I even used Z-bars with tack strips near the vinyl. It's suppose to help you fold over the carpet and make a nice edge. I couldn't get it to work and had to pull all those tack strips up. I just folded over the edge and stapled it down.
I put a piece of extra new carpet under my black chair, just so it wouldn't leave marks on the carpet. I also put down some carpet runners to protect the carpet from the rain this weekend.
I didn't do the steps. I've ordered sand colored vinyl to put on them, since they get most of the wetness from the rain and the dirt off your shoes. I'll try to get that done next week.
