When you're a painter for 10 years and this day would comes

I've done a lot of painting and I always wash my trays and other equipment when I'm done. I assume someone who does it for a living should be smart enough to take better care of their equipment. Besides dried paint in a paint tray still flakes and would contaminate the new paint poured on top of it, leaving chunks on the walls.

My dad's been a painter his whole life pretty much. He always cleans his equipment after painting.

you guys must be interior painters, I worked a job where I painted outside the buildings, we used this paint spewing machine
