zap a gap thickness

what is the difference between the thick and thin formula. i want it for glueing bead heads and popper bodies

Zap with the pink label is thin and dries quicker. Zap a Gap (green label) is thicker and fills in gaps in materials better. It is also slower drying and works better with an accelerator spray like Zip Kicker. Dries it instantly. The thin stuff tends to form a white haze when you “Kick” it. I prefer Zap a Gap as it forms a stronger bond.
