I don't understand your question. What Hobby stores are you visiting? All of them sell Metal Flake type paints, as a matter of fact, you will see more Metal Flake type paints than any other paints on their racks. If you want something heavy, try using the Testor's One Coat Lacquers, I personally don't like them but they will probably work for you. Michael's Craft Stores just brought a bunch of them in, I believe they have about 7 different colors to choose from.
This is a Charger I am building for a friend of mine, you can see the Testor's paint I am using and the results after adding some clear also. This is one of the colors from Michael's that I purchased.
