If you remember reading my Seat topic, those nozzles are exactly the kind l used first on my Seat crossdraft.
I decided to try and start makeing some progress today.
Cold temps and one eyesight forced me to work slowly but accuretly, and in all dedication my dearest wife came by, with a sharp “why are you makeing a mailbox?”
