Contact JMI RC Truck & Trailer Bodies at 1-253-561-9933
I just talked to him, BEFORE posting his information here. He has some, & is willing to sell you some of it. The product you'd receive WON'T have the JMI logo inside the tape, as does the sample video below, but it's the same tape.
Video link to see a sample of the tape, tape appears around the 3 minute mark in the video!
