I want to camo my 14' jon boat. Has anyone ever thought of using one of sponges you sponge paint your house with? I was thinking with a few colors I could break up the flat olive color a little. If i move the sponge around I would think it would give me a random enough pattern to break up the boat outline pretty good. I'm not an artist, and the stencil kits you see in cabelas/basspro are expensive. What do yall think? Any thoughts?
