I would kill for a good shop vac and dust deputy right now, I am tasked with cleaning out all the rails of the in floor frame rack in my school auto body shop and they have been open for probably a decade so there is a 2 by 3 inch steel channel that's full to the top with dirt, bolts, pencils and slide hammer studs and all rusted but the opening is only about a 3/4 inch slot running down the rails and I have to empty the shop vac at the end of each class in order for to have any suction left.
