If you are looking to paint model cars, spray cans are the way to go for starters. I would recommend testors lacquers or tamiya spray paint hobbytown should have those .as far as primers go ,duplicolor or plasticote are good ones.another place to find a good selection of spray paint would be auto parts stores .your post mentions a huey which I would imagine you would want to paint in flat olive drab or something similar which you could use enamel paints .perhaps a sporting goods store with a hunting section may have those colors. yes michaels does sell model cars and you can sign up online to get coupons for upto 40% off which is a good way to stock up .as far as glue I would recommend liquid cement from ambroid,tamiya or plastruct,applied sparingly with a brush. I have seen a few customized hot wheels cars around here but mostly 1/25th scale cars and trucks .good luck have fun and welcome aboard.
