The best option is probably going to be one of the few 2k (2-part) variants available in a rattle can.
R-M (BASF) has one called "Aero Max" 2k. The only other one I know of is called "Spray Max" 2K. Note, these 2-part aerosol clears are not cheap.
Second choice would probably be U-POL (Clear #1) witch is a 1k (1-part) clear, but good quality.
Also, on the lower black section, you might want to go with something like SEM Chip Guard (especially since it's a track car).
It comes in a rattle can, either black or clear.
