During another post there was mentioned the need for tool water protection of storage tools.
I was thinking that the tool storage area could have a sprig loaded cover that would just be pushed down when a tool is being picked up by the arm.
Or there could be a cover that is tall enough to let the arm in (pushing past weather strips) and out.
Either way there should be a gasket or something to keep attached tool dry as well. if not and they are put back wet freeing temps could cause issues.
Anyone got any ideas?
