applying filler

Ok after dressing both wounds the section from the new quarter skin and the top C pillar This is after 1 what I think is thin coat of Fiberglass filler. Mixed as I had seen in videos and directions on back of can. Then I took out my electric orbit sander with some 100 grit... Got it fairly smoothed down.


So next? Should I go back over with another coat of Fiberglass or move on to regular body filler? It didnt turn out all too bad and I believe I filled the low spots good and Feel like a skim coat of body filler will smooth it all out.

A few photos what do yall think?
