Has anyone done mirror glaze in a tiered cake? I am making a 4 tier cake and am thinking about pouring it over the whole thing, already assembled. Or should I mirror glaze each tier, then assemble? Any other tips with working with mirror glaze and cake tiers?

hello, I was watching video by Joshua John Russel mirror glaze tier cake. He glazed each tier separately and then assembled a cake. I would do the same way.
