I am not sure how to proceed and am open to suggestions. First, the photo is the front corner of our current build. 1 1/2" foam roof panels, 2" wall panels. The roof panels were glued down slightly over on one side, thus short on the other side. About 3/16" at the most. We're hoping to round over the edge. Haven't decided on a radius yet. It will be PMFd after filling/shaping.
Is it as simple as filling the kerfs with GS then Surfoaming the edge to the profile we hope to end with? We have to deal with the canvas seam as well. Probably about a two inch overlap of the wall.
Thanks, Tim
