Well, working in and around the paint department at Lowes, there are different sheens to paint. Gloss, Semi-Gloss, Satin, Egg Shell, Matte, Flat. Just subtle differrences in each one. Satin is a softer semi-gloss in my opinion. If you plan on weathering the bucker, leave it. If you want to stay a clean scout, I would hit it with semi-gloss coat like Frank said. When I had to repaint my KS bucket (never leave your bucket in your bin for a month after a sweaty SWW troop) due to yellowing, I just went with a straight high end high gloss and it turned out like I wanted. Ultimately, it's up to you.
