Yes, I'm pretty sure they do. I also seem to reacall Dave W putting a thread ( or at least a contribution to one) up about this.
Another approach might be ( geography permitting) to 'phone Kevin Vernon at Tudor Motors and ask if he can let you have a small bottle of touch up) you might have to take a run over to M. Drayton to collect- hence my comment about geography

PS if the car is a recent model, then the Factory now use Glasurit
