Have been annoyed that CorrosionX HD or Heavy Duty has only been available in an Aerosol Can or Gallons. In Australia aerosol means that it is shipped as a "Dangerous Goods". Can't fight City Hall is the expression. So with the arrival of CorrosionX HD in a Trigger bottle we have a product that ships easily. Using the country of origin measurements the aerosol was 12 oz and $35.00. The Trigger is 16 oz and $39.95 so it is better value for money. (How is that for protecting your assets.). Having used the gallons of the product and seeing how thick it is I wondered How? Would it really go through a Trigger spray bottle. So here it is.
