Trainwhiz20 and Interurban, Thanks for the comments. Yeah, I agree with you, Trainwhiz20 -- the foam lines are a bit visible on the mountain. This forum is exactly why we want to share our progress -- We appreciate you giving us honest feedback, and Interurbann we appreciate your great suggestion -- we'll try this technique shortly and hopefully will see the "seams" dissapear. Will post as soon as completed. Now that we have done the hydrocal thing on the base of some of our structures, we have confidence to try your technique on the mountain.
