Another Under Hood Insulation Question

[DT1]

I know this question has been asked before but after searching this and many other forums, I still can't find the answer I'm looking for.
I would like to insulate the underside of my hood and I'm looking for pictures and ideas of how others have done it. After looking all over the Web I've found that there are no pre-cut kits out there for these trucks so I'll have to custom make up something. How did you guys do yours? What kind of insulation did you use? Did you use some kind of fastening system or adhesive? Did you use an edge sealer or some sort of trim? I really want to make mine look and fit good. Please post Pics. I'm sure there are going to be some good examples right here on this forum.
