Not too sure I buy the idea that birds don't detect hot. Went to the beach last year and a relative brought some beef jerky that was some ungodly hot. One little taste and your mouth and throat was on fire for hours. Left the open bag on the picnic table. Now anyone who has spent any time on west coast beaches knows that seagulls will and do eat anything left out. They will open up closed bags of food and pretty much destroy your campsite. That open bag of jerky sat there on the table for 2 days; the seagulls came & investigated, shoved the bag around a bit, tasted it, and then left it alone and gave it a wide berth!
As for capsicum tape; It wouldn't be practical for a car owner to try to wrap their wiring; you couldn't get to all of it. Perhaps if the manufacturers used it for the wiring harness before the car was built?
