Well I'm with Julian....large container of ACF-50 and a hand spray bottle.

Re aerosol , Take it outside and stick an old set of compasses point through the side furthest away from you whilst holding it vertical, puncture near the top and you won't lose any of the contents. Don't be surprised if there's nothing pressure wise left in it. Before you start if you can squeeze the can between fingers and thumb then there's little or no pressure. if it's hard then the valve has failed but you can still depressurise it quite easily.


Now ..... shock absorbers that's another story!. As an apprentice I was sent out to drill a hole at the top to depressurise them and dump the oil in the wast container!

All I can say there is I worked with a load of bar stewards! Mind you, they were so awful to work with that they caused me to change my life. I ended up flying helicopters, They still Had oily rags in their pockets!
