I have used the GF extender with TC finish with no ill effects, Roger, but I cannot assure that it's chemically exactly the same. By description, it would be the same or similar as the Target product in function. Both "extend" the drying time slightly so that the finish can settle more for a smoother result. If the coating skins over too quickly in some conditions, it will not level properly.
