Geodesic foam scenery

About to get into the scenery stage and wondering if any of you have tried this resin technique. Watched a Demo by Bragdon Enterprises at a train show this month and I was very impressed.

My questions are, How well does it hold up, is it as easy as the demo, what problems have you had with it (the good and the bad), how many castings did you get from each mold, does the fine detail hold up.

I will probley go ahead and go this way, but like to find as much info as possable about it.

Thank you for yor time and effort…John
