I know this is late in the thread but this may help for future reference for everyone.
If it is latex paint you can soften it and remove it with alcohol, denatured. The alcohol will take any wax off but shouldn't hurt the clearcoat too much. If it is an oil based paint you can use a Naptha based cleaner similar (lighter fluid) to that used at body shops.
When all the heavy spatter is removed and there is still heavy staining you can try a cleaner polish. If that doesn't work you can wet-sand the clearcoat with 2000 grit paper, dual action polish, swirl remover and finally wax. You'll never know it happened.
One of the hardest things is to get clean is the trim and rubber mouldings. After cleaning the rubber treat it with 303 Aerospace Protectant. It is absolutely THE BEST you can do for your rubber bits including tires.
When all is said and done, this is MUCH better than a "key" job.
