I've used them on three two of my Dragon builds and my Tamiya Jagdpanther also has a set of DS Panther tracks fitted on it (I used Friuls on the Panther).
I paint them with Acrylics and use either oil based washes made with Artists White Spirit or ready to go MIG washes and have never had a problem.
I have heard of the early vinyl one piece tracks going brittle after being painted with Enamels but the tracks we get these days should be totally fine.
