Nascar does it all the time. They need to approve your sponsor and then they talk them into becoming an Official sponsor of the series. They did it to me twice and they do it to everyone. Is it right...nope but that's what they do. I have had drivers call me.and ask for my sponsors phone number...Talk about balls. There are ways to do things in a professional way and there are dirty underhanded ways. It's your choice, most sponsors know the difference.
