I've been powder coating bullets for years using the shake and bake method. However a buddy of mine showed me how he powder coats fishing lures using a fluid bed chamber to get an incredibly even thin coat of paint prior to baking in a toaster oven. His chamber is simple, but only a 3" diameter PVC tube with air pumped to to "fluidize" the powder. I'm thinking about trying this for boolits. Has anybody tried this? It seems common place for lure makers.
