I've been given a load of Tamiya paints, obviously quite old as a few show Richard Kohnstam Ltd as the supplier...
Some of them are coded PC "for polycarbonate".
Tamiya's website says that these paints should never be used on plastic, that they are designed only for use on the inside of polycarbonate body shells.
Does anyone know for sure if this is really the case and what happens if sprayed on normal plastic? Is there some sort of reaction.
If they are useless on polystyrene then I'll move them on to whoever wants them.
