I am trying to insulate my garage door so my 12K btu a/c will keep up. I have applied Reflectix foil insulation using carpet tape. It has plenty of grip until it heats up...then it gets very gooey and the insulation sags. A couple of sections have fallen off completly.
What type of tape or adhesive would give me a better bond that would hold up to the 100 degree plus metal surface? I'd like to have some chance of removing it at some point.
