Anothe example of why metal lath decks need fiberglass over the lath

Still on memory lane row, I found these pictures of a deck in Ventura with an ocean front exposure (at about 200′ above sea level, but not fog level)that are of a metal lath coating, brand unknown, with a rusted out lath. This deck system has no waterproofing apparent, no fiberglass, no seal guard, nothing, just relying on slope to run water off before it could percolate down…it didn’t work.
