I use an old kitchen knife I found for cutting bait. It's stainless, but the salt water keeps rusting it. I decided to powder coat it, and it turned out pretty good. While I was at it, I took a rusted spoon I had found in the water, cleaned it up and powder coated it white. I wanted a red stripe, but wasn't sure how to make a nice clean one. What I ended up doing was brushing some powder coat onto the glue side of a piece of scotch tape. After baking the white background to set it, I heated the spoon a little more over a heat gun, then laid the tape glue side down on the spoon. It melted right onto the spoon! Nice way to get a clean pattern onto a base coat.
