I chose Krylon because it’s commonly used on patio furniture, kids toys, and other stuff that gets abused, prodz — as opposed to finishes used in modelling. I figured I’d give Krylon Fusion a try since it’s inexpensive and gets favorable reviews. Durability is important, but I could live with it needing to be refinished after, say, a year. I believe the Fusion has a chemical reaction with the surface, so that it probably wouldn’t peel off. But we’ll see. What the heck, it’s just a melodica.
