HELP black roof marks

[tintopracer]

I haven't had time to clean my Cooper D for a couple of weeks. When I did get round to it yesterday, I noticed lots of little white marks on the black roof. I think they may be paint as my neighbours had their house painted a couple of weeks ago and when the decorator was rubbing down a lot of bits got on my car.

Any suggestions how to get rid? I tried a tiny amount of Autoglym tar remover but as it was hot and sunny I didn't want to risk rubbing it in too hard.

Would claying the car get rid if these smuts? I've tried to get some photo's but my camera's not great. Any tips on how to get rid of these unwanted marks much appreciated.

some clay should sort it, go down to halfords and buy a meguiars smooth surface kit
