I would not heat an aluminum racing seat above environmental in any manner.
Fairly thin seam welded sheets might not take well to being at 400+degrees. I would bet that would void any sanctioning/safety certifications, SFI, etc...
I have seen tons of various coverings, but don't think I have ever seen a coated or even painted seat in a sanctioned race car.
