Not in the shed but we used it in the workshop of a motorbike dealer I was working at. Laid it down about 5 years ago on an old and pretty grotty slab. I was in there last month to clean the place out and the paint still looked good. No major scratches or chipping and it got a fair workout. Used to get metal bike crates dragged around on it and the forklift driven on it occasionally. Can't remember which one we used unfortunately.
