I need to check, but I may be butt hurt because of this thread. Won't SOMEBODY stop this madness?
I didn't want to BS in the classifieds but there is one brand of heat tape and I can't think of the name, but it looks like stainless steel braiding over a blue electrical wire that I feel works the best. It is a scaled down version of what they use on the Alsakan pipeline. Morrow-Gill lumber in Sand Springs used to sell it.
And You don't know squat??
