What to re-cover blend doors with?

I'm in the process of restoring a 96 Volkswagen GTI, and as such, I removed the dash to get at the heater core/evap core for replacement. As I was in there, I noticed that the foam covering the blend doors was totally shot...missing, ripped, old and turning to dust. I've taken the blend doors out and cleaned them down to to bare aluminum. Now all I need to do is re-cover them and I'm good to go. But...what do I recover them with? Has anybody out there performed this type of repair before? And if so, what did you use to re-cover your blend doors? Foam? HVAC tape? Something else? My biggest concern is longevity. Whatever I re-cover my blend doors with, I want it to last. Pulling the dash/heater core out of a Volkswagen, is a task best done only once during a vehicles restoration. I sure don't want to do this again. Thanks for the help!!  

This is camper seal tape, found at Home Depot and other places. You might shop around and see if there are different brands available in case one would work better than the other. Sticky on one side, dense foam on the other.
