Now that I'm looking at my kitbash mentioned previously fresh this morning, it really isn't as bad as I thought.
I think I'm going to re-do the car. I know the parts I really screw up, and maybe re-do those areas.
Or, the whole car down, prime it, and repaint it with an airbrush machine and Testors paint.
Also, I'm going to take one of the blank cars I have now, mask the car approriately, and use the airbrush machine to create stripes.
Or maybe just tape or something else they may sell in a hobby supply, just have to look. I know I can do better with these and want to do better, just need the right experience and tools.
