I mean if the original stuff is stuck on well it is doing its job!!! It's only where there is visible evidence of rust underneath that is a problem. As soon as bare metal is exposed to the air rust starts. At the factory there isn't much time between the panels being welded up and the paint job. At home in the garage once you remove the original paint and if the car sits around for weeks rust will start (even if ya can't see it). Further, abrasive papers (or blasting) leave a rough surface which has more surface area hence more opportunity for rust. The original metal has a rolled surface off the sheet metal mill and is smooth. A panel prepared at home is going to have lots of micro rust on it. Do any of you advocate using (rust convertor) phosphoric acid on bare metal before using a primer? Phosphoric acid turns iron oxide into iron phosphate which does not oxidise??? If it aint broken leave it alone. David [Report message to a moderator]
