(I do pull off the clear layer of tape on top of the woven plastic, because it does make it easier to layer the tape and harder for the kiddos to pick it off.

Additionally, if the repaired or assembled item gets hot, as is the case for an item stashed in a car on a hot day in the sun, the two layers of the tape will expand at different rates resulting in heaved-up areas of the clear top layer while the black base layer stays mostly where it was applied.

On top of that is a clear layer which leaves the surface surprisingly slick.
