I imagine some customizers don't like giving away the "secrets" to thier work but I have a question that I hope has a simple answer. My two oldest sons (12 and 7) and I like to re-paint many of our 1/64 cars. (Hotwheels in particular.) What is the recommended way to re-attach the base to the car once we have completed the re-paint? We've tried several methods but aren't having terrific luck. Also, we are interested in swapping wheels on some cars but have noticed that some require the axles to be shortened. What can be done in this instance? I'm not sure how mattel does the axles on the Hot Wheels cars. Any and all info provided will certainly be greatly appreciated. My sons and I thank you.
