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?


Also, If you are able to, do your filler work with 36 grit, it will pay off in the end. Then finish with 80 grit and lastly 180.
