Well, it looks awesome!
A trick I use is to cover the car with an old model display cover while the paint dries.
(In this case a Future clearcoat. If you look really close there are paint bottles under the body keeping it off the towel.)
There are other tricks like remembering to wipe the car with lint free cloth before painting and not painting where your finished parts are.
The real question is what is the next project? That was a cool build!
