Not all Urethanes are created equal. That's a problem with "Cheap" internet paints, and great deals. Just because the paint is cheap doesn't mean it any good. You can spend $330 for a complete paint "kit" and be repainting your truck in a couple of years.
Ever seen a Maaco paint job after a couple of years. That's why they can paint a car so cheap. CHEAP paint.
So save yourself a lot of grief and use a quality paint the first time around.
