No, it's a day and night contrast from cut to un-cut primer (sanded and untouched)

No "guide coat" needed here. See how dark the door is? I havent touched that door yet with the sandpaper. So the areas that the block foats over remain dark like that door.

Here you can see WHY I surface and block sand.

Brand new steel isn't perfect. I have high and low spots. Granted it's ever so minor, but this block sanding shows it all. I will be hitting these big long quarters with another coat of polyester prime and re-blocking before final prime.


Something clever here.
