You sneaky devil, you've had the answers for a while. It's cool! It's funny to see the responses to the orange foam question at L2, It's exactly as I said, goes on light, turns dark after exposure. I know this, it's unclassified, and has been for a long time. People see my "beginner" tag an assume I know nothing. 20 years in the USAF, two degrees, and my credentials mean nearly nothing. The SLS model looks great! Keep up the great work. See ya in the threads, and on L2.
