"...the first hand heat does not penetrate the jeans over the carpet and will, I repeat will melt the glue beads on the tape." Absolutely, 100% physically impossible. The heat must transfer to the jeans, through the carpet, and then to the glue. The transfer is not 100% complete, hence, some is lost in the jeans and the carpet not to mention the air. Therefore, the iron must be somewhat hotter as a result of all that heat loss just to melt the glue vs. the standard glue iron. I would love to see what 100% nylon carpet looked like after all the heat transfer.
