the car wash just doesn't do anything for me

I need to pick up a claybar, but i didn't think that would actually help with the bugs/dirt. I picked up some of the new turtle wax, we'll see how it does. But, i still just don't know how to get this shit off the car...i'm using one of those mitts to scrub with. Is there anything rougher to scuff it out without harming the clear/paint coats?
