Mixed 60 mL to 32 oz water. Working well on mild steel,aluminum and cast iron. Corrosion inhibitor works very well with no sticky residue on parts

Works well. No smell. Keeps lathe and mill clean

Works very well at a cheap price Not intended for mister system

Using it in a Jet metal bandsaw works very well....would buy again.

Does what you need it to do.

I read through some of the comments on the mix ratio and settled on trying 5 oz per gallon. Ran my mill in the evening and shut down. In the morning I came into shop and the mill had started to rust. I cleaned that up and increased my concentration to about 1/3 of a gallon of Trim to 4 gallons of water. That works pretty good but I still see a little bit of tendency to rust here and there. Thus I am going to use a full half gallon of Trim to 4 gallons of water. That might be a bit heavy, but rust is no fun! I spent about 20 years in the machine shop in one career. that ended in 1994. So I have seen my fair share of coolant. I would say Trim does a nice job and is pleasant to work with vs what we used back in the day. But do watch your concentration level! P

Wide range of effective concentration. Stays emulsified well with intermittent use a few weeks in between. Has almost no smell and hasn’t cause any skin issues. Protects the metal well, the mild steel filings I left on my bandsaw have little to no rust which was surprising to me.

Been using it for a while machine is not rusting

I like the ease of use, lubricity, smell and clean up. I have had no issues with this lubricant and no rust issues either.
