I have a question. I am just now getting to putting my box of parts together (ie. the stang) and I am wondering how to address the parts that come from the "original tooling" company. They are all "painted" black. Should I strip this coating off and start over, or can I just sand and spray the omni on? Pro painters please help. I have gone to a ton of work on this car and I don't want the Paint job to be the reason the project falls on it's face. Thanks for the input.
