Little extra research:
- http://www.allendale-stores.co.uk/docs/psold/electric-paint-datasheet.pdf $15 for a tube. But it can wash away with water. Not sure if it will last.
- There are many options on Amazon.com (as always) and cheap, nothing that ships to AUS yet. Next time I head to US, might order one of these to fix it.
- or next time in Dublin, maybe look for parts.
