i have been in and around the autobody business my whole life, the past ten years i have been working at a major autobody paint supplier, We sell many brands of paint including Dupont. Dupont is good, as 8secdart stated, yes the coverage is not that good, but still a quality paint. What makes paint chip easily is poor surface prep or too thick of a film build. that said, engine comp and jambs should be prepped very well and minimal film build in these areas to insure good resistance to chipping
