The glue is BLUE when wet but turns CLEAR when dry! Full instructions are on each pen.
The wet bond is permanent - obtain a wet bond by pressing the two surfaces together immediately after applying the adhesive (make the bond while the glue is blue).
The dry bond is temporary and repositionable - for a dry only apply lightly and use when the adhesive is dry (make the bond after the glue turns clear).
