I had this happen to me as well except it was accidental. What will get it off depends on how long it has been on there. Its very important you get it off asap before the sun cooks it in better. With mine it was 4 days before I could do it due to my typical bad luck and unforseen circumstances. I had to use lacquer thinner and my clear coat is now fugged up badly. If you can get to it quick I would go with the suggestion of the clay bar or goof off first and pray for the best. Good luck.
