Interior: Dynamat cover?

[mdeal]

Guys, I need some advice. I'm overhauling the interior on my 71 C10 "shop truck". This is by no way a high dollar build, but I have done some nice touches and I believe the right way. My question is, after you use Dynamat(or whatever brand shiny silver insulation) and you have covered up the firewall, floorboard, and up behind the seat; then what do you cover the said Dynamat with that is not covered by the replacement carpet? That was the world's longest run on sentence... I don't really want to see shiny silver aluminum foil behind my seat(tank has been relocated) nor do I want to see it above the carpet line under the dash.
Any ideas?
Carpet? Spray paint?haha.

Examples with pictures would be great! Thanks!
