Even in WWII, most countries had good quality control for the base paint on vehicles. Yes paint would chip, but nowhere near as much as seen on the current "trendy" models. Look at actual WWII photos and chipping is minimal to non existant in most cases. WWII vehicles had short service lives, often only months long before they were destroyed, lost, or replaced. Dirty, dusty, and muddy, yes. Chipped, maybe if they have been thru a few fights and survived. If you are a vet, think back to your service time and how vehicles you served on or around looked. You wont go wrong from that starting point.
