freight shaker

Hi everybody, NewB here.
I've got an 03 silverado with a scratch in the door & I was wondering if the duplicolor scratch fix kit is worth a crap. I don't want to spend too much money at a bodyshop so i thought I would try this. It's only a work truck but I like to keep it looking halfways presentable. Has anybody ever used this stuff. I'm not sure If i should follow all the steps (sand,paint,clear,sand,polish) or just go over the scratch with the paint pen. I hate looking at that scratch but I don't want to risk making it look worse than it already is.

any help, thanks.

sure, I'll see if I can snap a pic in the next day or so. It's in the passenger side door about 6" long, It's into the metal but it isn't rusting......yet.
