I did the first 2 heat tape pieces today. I have 8 left, it s a 10 slot rack. It wasnt very easy actualy, Ic ount get the heat tape silver strip on the side to melt and burn the wire into it. How do you all do it??

On a side note, I also melted a bunch of holes in some plastic, the melted plastic got stuck on the soldering iron tip, now it is dry. How do I get that off?
