If you have a truck that is very well restored, why would you consider the poor quality out of a spray can. The job will look good as far as when you spray it, but it won't last. Consider the weather elements, and the fact that they are running boards. Don't go cheap, as they are attached to other parts of your truck and you will pay the price for being cheap. You might consider powder coating them. Coat them with POR-15 on the underside and spend the money on the top side. If you go cheap, you will regret it.
