High-temp spray paint: 3 spritzes (N StL Blvd)

...in cream/off-white/almond (I have white-white). I only need 3 small spritzes and hate to buy a whole can. The high-heat type that goes on radiators or barbecues (but not the kind for barbecue propane tanks which stay cool). Will gladly do a porch pick-up and porch drop-off return at yr convenience. Note: I don't keep a constant internet connection, so kindly allow time delay for replies. Thank you.
