Kind of strange because real duct tape sticks to almost anything if clean and dry. Try cleaning the surfaces with denatured alcohol (paint departments) or at least the 90% isopropyl alcohol and let it dry for a few minutes before taping. I've used laquer thinner at times on unpainted metals and some plastics but on some materials like the foam it will dissolve it. The only duct tape I ever used was the plain old gray stuff from Home Depot or equivalent. Never saw other colors.
