Somone correct me if Im wrong but the reason for no Detail Spray is because it actually has a sealer in it of some kind and there is also really no reason to clay fresh paint. It won't have any contaminates on it coming right out of the booth and coming from the body shop it shouldn't need polished because again fresh paint shouldn't have swirls in it. If they needed to do any sanding (in case of runs, dirt nibs, etc.) they would buff it before it leaves the shop.
