Sixgun...
I havent used the Krylon paints but have seen some paint jobs with em, they do look good. The satin finish is in between flat ....which is a finish with absolutely no reflection. Satin has a soft lusture, not flat nor shiny either. Gloss is of course shiny and will have reflection properties. The satin is a good compromise between the two.
I have a couple I have painted with regular satin spray paints in "camo" colors and they are ok. Over time they do get scratched and will require repainting but that's no big deal. If you get bored with a particualr scheme it's easy to do it all over. Here is a picture of a Mc Millan stocked custom M700. It was originally a solid grey(should have had a Mc Millan camo finish) and I wanted something different. Not the best job in the world but it works for me.
