Over the years I've stored many hoods by simply wrapping cardboard around each corner, taping it in place & leaning them up on the wall with sheets of cardboard or rigid foam in between them. Never do I ever put them on the ground with the cowl edge down, they are always on blocks of wood & on the left or right edge. The hood latches & associated parts are removed & kept in a box labeled for each one so there's no chance that one hood will be dented or gouged by another. Stretch film is cheap, a roll at Home Depot & Lowes is like $20 & is great to wrap edges to help keep the cardboard corner protectors on. A rope to keep them from tipping over is a good precaution.

Now that I think about it I bet I have 10 or 12 hoods in stock....LOL
