So its inconsistent even from one identical car to another. I must have been lucky with all the ones but those two. But others have posted about this in the past, especially the '70 Camaros, so I guess you should try one method, then the other if needed.
By the way, you will be happier with the finish if you use #1000 grit abrasive disks. They are backed with soft foam and last forever. Not enough grit for shaping, but its great for finish work. You can even take off drips or orange peel with it, then paint right over what you had. You get it at woodworking suppliers online, like Woodworkers Supply. I use it to take off the ridge that sometimes happens when masking tape is pulled. When the clearcoat or Future is applied, you can't tell it was ever sanded.
