I am going to have to rely on you guy's knowledge again for this one. You know how the back of the cab has those... well we'll just call them ridges. It's not straight and smooth by any means. I am wanting to coat that whole area with some sound deadener I bought. That's the easy part. That doesn't need to look very good, or professional like. It just has to get the job done. But then, of course a person would need carpet it after that. You can't just leave that stuff showing, it looks bad and without the carpet covering it, it's just going to get holes and eventually get torn up. It's not made to take any abuse, unlike the carpet that covers it.
So how can you get the carpet to properly fill in all these ridges, when they are so uneven like that? Cut up the carpet and just sort of stuff it up in there? Since the ridges don't reach all the way to the top, you can't just sort of roll the carpet out on top of the adhesive. You would have air pockets. Hopefully someone who has done this before will see this thread and post up some pics of their carpeted back wall.
