Sorry for the lack of updates.The old iPhone that I was using for photos died and I can't retrieve the photo's.The urethane pour foam support worked great to support the fiberglass during the concrete pour.After the concrete cured for a couple of days we used a fork lift and invert the hammer form.The temporary urethane form was discarded and it did it's job .It kept the fiberglass surface true with no distortion .I will continue the progress report with photos from my new phone.
