Ya'll keep an eye on those PDR dents. When the rust starts, and the paint flakes. Call 'em back, and see what they'll do about it. Nuttin', Nada, Zilch. An' now you get to eat the cost of a proper repair.
See, what happens, is the paint flexes with the dent, when flexed back it cracks. You can't see the cracks some times, but they're there. Look close, under flourescent light, you'll find them. Moisture gets in there, and corrosion starts, and there ya go.
