Rust
(I've noticed this progress of design by rebuilding many different year model classic cars, from older cars with no obvious drain hole technology to newer cars which have complex systems of self rinse design) |
(The early style AMC Metropolitan unibody chassis had no 'strategic' drain holes to allow water to drain out of the frame channels, moreover they were bare metal inside/not dipped in primer or paint to prevent rust) |

| + | *Electrolysis due to some older cars (British) having 'positive ground' electrical systems -where the car's electrical system is basically all 'ground wires' instead. (eg: AMC Metropolitan assembled by Austin Motor Company in Longbridge, England -neither were they dipped in a rust preventing primer bath, then they were shipped in ocean salt air to be sold in USA) | ||
