What happens here

Take a 3M medium grit sanding sponge and lightly scuff the entire surface of the new metal door. Since the door is factory-primed and can be slick or glossy, this light sanding creates a better profile for the DTM bonding primer to adhere to. After sanding, thoroughly dust off the door to remove any sanding residue.

Goal: Begin by lightly sanding the entire surface of the new, pre-primed door using a 3M sanding sponge. This step is crucial for dulling any slick or glossy areas and preparing the surface for optimal primer adhesion.

loaded up right here. Do a light sand of the door with the 3M sanding sponge. It's a brand new door. It's pretty slick, glossy. Light sand. And then we're going to spray our primer on it. We're going to stand it up so we can spray the primer on both sides of it quickly. We're doing the exterior of this house right now also. But so we got a drop set up and masking. So it's a good place to actually prime the door. If you prime one side, you could flip it, turn it, and prime the other side.
