Been working on filling in the very small seams between the foam sheets so you can't see them. Resin, or Hot glue did not work real good. But, bondo glazing & spot putty did the job. A little lite sanding, some plasti-dip, and you can't see the seams any more. I would take some pics, but my camera won't let me get that close for a good pic. So if your working with foam try this. Hope this helps out.
