Doing some car repairs, and those are the three basic substances I’ve decided to use. I’m sure I can get a decent rust remover from an auto shop, but I don’t know where I can get the liquid CO2. Anyone have an idea? The store doesn’t have to carry all three items.
Liquid CO2 is not something you want to use. The danger of frostbite from even momentary exposure is extreme, and there are a lot of related hazards. Check out the MSDS below.
