Fairing means either removing or adding material to smooth the contours of the surface in preparation for finish.
I think feathering is the proper term for preparing the divot for the repair.
On your project that would mean filling the depression left by the departed gelcoat. It can be done with gelcoat or resin, thickened to a putty with cabosil, then troweled on and block sanded to match the adjoining surfaces, in preparation for application of finish.

 

So put A light on it for 3 days and its all cured. I also used a syringe to see how many drops it would take to get 0.6 ml and it took about 21 drops so with that being said @ 1oz of gel I had half the hardener required. So from now I will be measuring the hardener out and not use the drop method...
