Just out of interest , who uses it and which sort . I refuse to pay for the aerosol type and buy 25 litres at a time and spray it through used flash bottles from home .
Hello Martyn, I think your bulk buying my be the cheaper option,Lots of the USA welders use spray cooking oil, They recon it's pretty good but I don't know what the cost is,
i use 'binzel' 25l drums,i store it outside & am not sure i should continue to do this side of winter as it does curdle & blocks the spray nozzle,btw its water based.
