Well someone ought to reach out and ask Marcelo Barbosa what he used for his MM interior. It really does look like Plastisol but even if not does seem a fine replacement. More so if it has held up over continued use.
Love how he has loaded bowls around the lower rack of dw. As we have porridge each morning for breakfast there are always lots of bowls but little space. While the manual says to load as seen above find it can lead to yibbles being left on the back of bowls as they cannot drain properly after rinse. Think results are better when bowls can incline forwards as they do in most all modern dishwashers.
