Yes, it's clean. Just have to be sure the final wax and grease remover application is with a product approved by the painter. Of course, that's if I do anything. The painter gets the final say. I don't want to hear that the stuff I used made the paint lift.
I hope to be able to make a decision on the painter soon. I've done as much prep as I can. Just waiting for t-day weekend to be over, then I start shopping for the biggest Christmas present I've ever had!
Any painter who knows what they are doing will go over the car and look for issues before scuffing questionable areas and cleaning. I don't know what quality you are going for but it would be worthwhile to let them prime and block the car too.
