stop giving logics,tell something practical 
btw what should be better
first GC then #26 after 2hr or 24hr
or
first #26 n then GC after 2 or 24hr?
so far em using both on weekly basis but this time em thinking to give it treat of #26,last coat was also of #26
GC is a dust magnet,attracts dust of a week in a day
