Ditto. This (person I know) entire second floor is stuffed with kits. Walls are stacked from floor to ceiling. The rest of that room is all shelves, also stacked up to the beams. Both levels of his two-car garage/barn are packed. You can park a car in each bay, but the walls are covered, except for a workbench. The staircase between the two barn floors is unpassable. In the main house, a few walls are covered. I would say about 1/3 of the open shelving in his kitchen is stuffed with Dupli-Color spray cans. His work bench is between the kitchen & living room. It too is surrounded with kits.
A year ago January, I fell down his main staircase. Broke my ankle. Fortunately, his wall of kits, and boxes of spare parts prevented me from slamming into the wall. I remember picking up wheels and other parts off of myself, and the floor. I would say the house contains between 7000 to 10,000 kits.
Now THAT'S a hoarder.
