I found perfect paint bombs in ausie post red at supercheap auto.

The brand is 'Power plus'
Code PJ5250, SNB150  RioRouge Red

I was lucky it was a perfect match, as the cap colour/color is much darker.

Parts must be very clean, it hated old texter, oil,  grease ect, and don't splash it with anything for 3 months till it hardens.

If you want to touch up small wear spots on the plastic, try some red indelible ink pens and a light buff with ultra fine sandpaper.
