Those wheels look sweet, and would be a great off-season project. I looked at the smooth-on site that you mentioned, and found a wide variety of products. Can you tell me exactly which silicone (for the mold) and which urethane (for the wheel) you used? Is it the smooth-cast 305 plastic in the 00M00 30 silicone rubber as shown in their video? Also, what type of fiberglass did you add? Thanks in advance.
