My bet is we get the C8R since it races both in the US with IMSA and in Europe with the WEC. Both groups will consolidate these cars into a GT3 class in the near future so it would have a broad appeal to both markets.
Thanks for the pics. A couple of our Corvette Legends (Dallas, TX) club members are crewing for 1 of the cars in this race. I am not sure if it is the 62 Vette you show above or not.
I tried the Tamiya white putty but it was too thick to get into the wholes. The super thin CA fills the holes just by using a tooth pick to spread it. When dry it is as strong as the resin. No chance for ghost marks when painting.
I do use the slow curing resin. Since I don't have the pressure pot I am using a syringe through a small hole to get the resin everywhere in the mold. I have done this on previous bodies and it worked well.
In my case I am doing the casting. I think I caused the problem because I used spray on mold release and didn't brush the body to break down the bubbles caused by the propellant.
