Not too impressed with the product.  On a fully dry acrylic surface used the tape for some additional lines.  I used the “delicate surface” variation because I was afraid of lifting off the acrylic paint.

Results:

• Paint bleed.
• The tape left a gummy residue that I had to remove by rubbing the surface.  The surface came out fine but again could have done without the left over residue.

Lesson:

• Just use my normal tack painters blue and prior to putting it on the surface of the model, tape it against your shirt or pants a couple of times to lessen the tack.

ADDENDUM:
