Here is what he said about the process.
"Have had numerous people wanting to know how to chrome soft plastics, so here is my way. Am sure others can come up with other techniques. I use a black bait straight from the mold with no oils added. You want a dry bait. Dark colored baits work best, but you can use any bait and improve your catch ratio. You can mix aluminum powder in color tech clear and spray your bait and coming back over it with white pearl in the color tech clear. This gives the bait a metallic silver-chrome look which is very durable.If you don't want to invest in an airbrush, you can mix your aluminum-clear and your white pearl in seperate containers and just mop a coat of each on the bait with a q-tip,etc. You can bypass the aluminum and put a coat or two of the white pearl on the bait, which I really like. A real plus to this method is you can use other pearls to achieve other metallic colors such as gold,etc.You can custom paint a bait with several colors as there is no end to the metallic color schemes you can produce. You can take a clear bait with weedless hook slot and coat the inner portion to get a highly reflective-magnified flash,also. Hope you like it. Do this outside or with proper safety procedures, as the fumes are potent. Keep it off your hands. I also have just hand rubbed the baits with the white pearl and dip the whole bait in color tech clear and hang to dry..."
