Deburred, Dimpled and Primed all parts of the Firewall. Used combination of squeezer and DRDT to dimple. Found it was easier to use the DRDT. Next airplane. I didn't prime the stainless steel, didn't see the point in that. Used Mike S.'s technique of using a popcycle stick to get the distance from the 601J's to the bottom stiffner (601M?)
