PocketRocket, high-temp aerosol paints can be purchase from any hardware shops & priced ard RM 12-15 depending on brands. Most of it able to withstand temperature up to 1000 F & it's available in 3 colors (flat black, dark maroon orange & silver).
Btw, i dun think that it's a good idea to spray ur bonnet with these high-temp paints as it'll look like shit as i've personally tried 2 months ago. Now my bonnet looked like farked up piece of metal plate nia. *Sigh* :cry_smile:
