Does a product exist that acts like liquid electrical tape for
resealing cracks in wiring insulation?   I've come across so many
places where electrical tape is too hard to wrap or places where I
can't slip heat shrink over because of a large connector.
I once tried Seam Sealant for sealing tent seams on a crack but it
didn't seem to last.
Would be cool if there was some way to "dab" on something to seal
things up.
