Aeropoxy is white, Vpoxy is clear
Aeropoxy is totally thixotropic - i.e. it will not run or sag. Vpoxy is slightly less thixotropic - thus it may penetrate some materials better.
Aeropoxy initial setup time is about 3 hours at 75°F. Vpoxy initial setup time is about 1 hour at 75°F.
Technical data on the strength properties of both glues render them about the same.
Aeropoxy and/or Vpoxy are Aerospace grade adhesives and the strongest epoxy based glues available to the modeler.
