FWIW.... On one of the FB groups somebody was using white epoxy primer and adding West Systems 410 microlight filler. I believe he mixed equal VOLUME of filler and primer. It was used as a high build primer. Very easy sanding and very little weight gain. A normal mix of primer was then used as a white base to paint on.

The Divergent is looking very good Shawn! Can't wait for it to get some clear on and assembled.
