Look if Toyota say used a full zinc rich primer, placed on top of hexvalent chrome sealer, then top coated primer with a quality high voc coating and finished off with a nice gma or similar, these trucks wouldnt rust.
INcrease paint thickness doesnt always correlate with increased mechanical properties of the coating, in fact often times higher dry film thickness equates to poorer mechanical properties.
You didnt hear anybody grumbling about cadium arsenic chrome lead based coatings..they were great!

i didn't say they weren't better paints, i said water based paints are fine and plenty of manufacturers and are perfectly fine today. the change over started decades ago, we're at least a decade past everyone using water based paints and we've made it through the growing pains of flaking clear coats. the paint on the 4runner is notable bad even among other contemporary water based paints, it is very thin and scratches easily.
