I don't know much on this, but I'd say rough up the paint that's already there to get the new paint to stick better.Aside from that, I have no idea,

thermo plastic is plastic not paint...hydro blast it off and re-apply fresh thermo.
if it's just road marking paint with glass bead you can hydo blast it or just repaint over it
