I needed a couple of barrels for my set up and time was running out so I came up with this.
First I went to the grocery store and bought a couple of these.
Then got some buddies and drank them. After the fun part, came the work. Pull out the vent in the top and the tap on the bottom side. Rinse the can out with water and let it dry out. Next give it a light sanding with some 120 grit sand paper and spray with flat black enamel so it looks like this.
Paint it with a dark brown flat paint. I used a dark chocolate latex I picked up off the mis-tint paint counter at Home Depot on the cheap. That is where I get a lot of my prop paints. It should then be looking like this about now.
Next use a lighter brown to paint a faux wood grain. If your not sure how to do this, do some internet research on it and practice on some cardboard so you get this look.
Now all you have to do is paint on some metal bands. Here I used a pewter acrylic and highlighted it with some silver on the finished barrels. You could leave it at that or paint on what ever you want it to be inside the barrel. Have fun and let your imagination run with it.
