The paints you get from TSC and the sort arent the greatest paints to use.
JD Blitz Black is a good paint to use, it is very strong, they use it on the lower portion of the cabs, the part that runs by the wheels.
The downside to it, it is tough so it doesnt sand easily to paint over, so down the line you are still gonna want to strip it to lay down real paint.
But if you're looking for a cheap long term paint, I would say this is the way to go.
