I do not see any resin going into the repair

The repair is not taking resin in.

Step # 1

First add a couple drops of resin to the Crack Eraser injector and perform a pressure and vacuum cycle.

Step # 2 

Next try pushing down on the injector to increase the pressure of the resin going into the repair damage. Pressure down also flexes the legs open to allow the resin more room to penetrate. 

Step # 3 

If the repair is still not filling the problem is probably that the repair does not have a good path way for the resin to follow. This is usually because the repair needed to be drilled first of drilled and tapped to create a path for a better entrance for resin. Some times you can cure the repair fully then re drill and tap to create a new path. Drilling and taping works best for this procedure.
