Same here, and there's also a easier way to do this. I was going to post it earlier but didn't. Make a selection with the lasso tool where you want there to be a radial blur. (if it's a big selection feather it about 15 pixels to clean up messy areas, if it's small feather it about 5 pxiels) Copy your bottom layer and radial blur the selection, reduce the opacity of the top layer to reduce the radial blur.
