So, they can but a tool and compressor, or use one of the not as easy but less costly methods available to them.
There's one at every auto shop in the country, as they're useful for all sorts of things on cars, particularly older, rusting cars. People used to come into the shop I used to run with all sorts of strange little mechanical problems that were solved by the application of an air tool. Some places, paying a mechanic shop rate to do that would be the fastest way of getting it done.
