Q: What material did SpaceX find in the engine release valve? Are the engines for Crew-1 from the same production line as the problematic ones?
Koenigsmann: "It was described to me as a lacquer, basically a nail polish I think is a good analogy. In this case it had a red color."

Koenigsmann further breaks down the sequence that caused the auto-abort for GPS-III SV04: "It's not necessarily bad in most cases for the engine but, in extreme cases, it may cause damage to the engine."
NASA's Stich adds that use of this lacquer "is very standard in aerospace."
Stich: "SpaceX moved very quickly when they found the problem ... they worked with the vendor to improve the process. They're going to work to improve their production."
"SpaceX shared all those corrective actions with us, working side by side with us."
