Door Panel Scratch Repair?

Just recently I took a spirited turn and had a metal object in my back seat shoot across and scuff the rear right door panel along with the window switch bezel. The bezel isn't a big deal since its a twenty bucks brand new on eBay so I went ahead and ordered that. That's also pretty fortunate considering it took brunt of the hit. As for the remaining damage it's just a couple scratches but enough to annoy me. So is there any way to smooth out/ fill the scratches and then repaint it? I know scratchwizard had a kit and a couple videos detailing the process but they done offer it anymore. l'm just looking for some insight before I tackle this.
