That was almost my suggestion.

While I'm not familiar with the metric packing standard for paint, I'm guessing that you have 4 cans of paint. If you take a couple of pieces of timber 20 cm wide and about a meter long you could make a very nice book shelf for the shed. Put the timber across two of the cans. Put the remaining two cans on top of the timber and the second piece of timber on top of the lot.
