Tightened everything as much as i really can, well, without resorting to pliers to tighten it further (got none pliers lying around though) lol
I just totally covered the top of the can in tape trying to seal it all, but there still some escaping, and the can got extremely cold pretty quick lol
I really have no idea whether its the regulator/adaptor which ive screwed on, or if its a problem with the can itself.
I guess these compressors have a lot going for them lol but if im being honest, if i cant get this to work, it'll be back to a brush for a good while as i cant really afford a compressor/better airbrush at the moment

feel like throwing the bloody thing in the bin and just forgetting about it lol
