Radiator paint

[Faze2]

Hi. 
Another newbie question:
I’ve bought a tidy 2003 fzs. The only issue with the appearance is the paint has flaked off the aluminium ends of the radiator. (Not the grills or end covers) 

Any recommendations for the best paint that’ll stick to the aluminium and withstand the heat?

Thanks. 

Hi i painted my radiator cover with a spray brake caliper paint, worked a treat.
