New racecar nearing completion

Not to be Sad Sally here, but you might want to check your local track rules on that powder coated chassis. A lot of sanctioning bodies are not allowing it anymore because it prohibits thorough weld inspections.
Really no different than paint or what people could do with body filler and paint if they were really sinister! Just like with paint if there ever was a concern the paint or powder coat could be easily removed for a thorough inspection. Also, the car already has an NHRA 8.50 tag on it (after powder coating) and the cage was sonic tested at that time.
