I think the new Evo long termer is frozen grey so these should be available in Europe as well? I've gone off matt black but grey is definitely growing on me...
1 Never polish or wax the frozen grey paint as it could lead to a glossy surface.
2 If washing your frozen gray M3 in a automatic car wash (you should be killed) choose a car wash that does not apply vehicle wax.
3 Rinse the M3 with high pressure water to remove dirt before sending it through the automatic car wash to avoid scratches from sand, dust and other micro-particles.
4 Remove bugs, bird poo, tree sap, tar, fuel spills or oil immediately using a soft sponge.
5 Avoid strong rubbing while cleaning the frozen paint. BMW sells suitable products for maintaining the frozen paint at your local dealer.
6 Repairs to the paint (scratches, dents, etching) must be completed by a BMW trained body shop. Most auto body shop will not be capable of repairing the frozen grey paint.
