Looks great Mike.  Sure is a lot of freight doors to paint.  Have fun.

I use lightweight spackling made by Dap. I found it in Home Depot but you can probably find it in any hardware store. I use the back side of # 17 X-acto blade as a putty knife. Apply the spackle to the brick leaving only spackle in the joints and not on the face of the brick. Sometimes after it dries I go over the surface with a damp sponge if there is some haze on the surface of the brick.

Thanks Rob, There are 20 doors and 10 (7 sets per window 56 panes) windows. To much to mask. Next painting all those windows and doors.
