Galvanised is the way to go if you want longevity. However, adding extra protection with underseals plays a big part too but even then it needs regular inspection and topping up. Waxoil, Bilt Humber ( what I ised) give that added layer.
Didn't the epoxy type paint used on the ARP cars start to break down? The Bilt Humber coating didn't harden so resisted chipping and peeling. I also sprayed the wooden rear inner wings/wheel arches with it. Aerosol or bulk with a Shutz gun/compressed air. Eastwood black chassis paint was used on the rear axle, various metal bits and even the wooden floor. Bought from Frost.
A hands on attitude helps with Morgans, otherwise get someone to do it.
