Anybody know where to get the heat-applied seam tape used in waders?
Sometimes you get a foot or two with the waders, but I'd like to find it
in bigger lengths

Scroll down a bit.

I ordered from these folks once a few years ago when making a large tarp.

But... have you considered using a glue like McNett's Seam Grip instead?
Works wonderfully well and there's no ironing.
