Yeah, but where do you find a ship that needs a round door and a steering wheel?
Just glue some of HF, Bed Bath & Beyond, Walmart, you name it, non skid shelf paper to one side. I've been doing that for years. One of the poor things gets left out in the weather, no protection from the elements, 365 days a year and it has been doing it for years. It even sticks on a slight down slope because the door holds it down.
You are probably going to have to explain them to some of the people.
I think they are neat.
Enjoy,
