There have been a few posts regarding Skorpion paint colors,and I have come across a suitable paint for the Skorpion yellow,(RAL1003)
It is made for plastic car models and it is available in small bottles for a brush(touch up) or spray can.
I found it at an arts and crafts place by accident..seemed a close match so I bought a small bottle..sure enough,almost perfect.
It is made by Testors and the code is 1114..so if anyone is looking to do small repairs,try it.
