Dan , I think the basic rule of nose that needs to be considered in CA finishes , is that if you can smell it while sanding or Micromeshing , it definitely isn`t fully cured . If it isn`t fully cured , the potential for development of an orange peel appearance days or weeks after sanding exists . I think there are two reasons for this - the first is that the finish is never totally uniform in thickness on the pen and thicker areas will cure slower , and second , nucleation of the x-linking reaction is never totally uniform , whether accelerated or not .
So I guess the bottom line is , if you are doing thin finishes , you can probably get away with nearly immediate Micromeshing . If you deliberately or accidentally over turned by several thou and are building back up with CA , or are doing something like a corn cob where the thickness varies around the kernels , it is probably best to wait several days before final sanding . Of course any finish , regardless of technique used , will be good if it is never looked at in the cold light of day several weeks down the road .
