Al Fista 1/17/2012If it is hard plastic, clean it with a rag and toluene carefully. Test an area 1st, and do be careful around painted lettering or decals. Then seal with a spray paint of the appropriate color. Alfas had a similar problem, the overhead console would get sticky and transfer color to your fingers. Some time later it would crumble.
