Sure, i meant if you are doing work repeatedly.

People often put the cartridges in a plastic (or sometimes mylar if they are advanced) bag to save money, and change them when they can smell stuff. This is a bad plan with isocyanate.

Auto finishes are moving towards iso-free 2k urethanes anyway. (wood will get there, but tends to lag)

PU is about the last coating I'd like to see on my food utensils. Not very interested in a daily dose of microplastics injected directly into my food...
