Was using this for car model, and squeezed one drop onto the part. As I pressed the parts together some of the glue got onto my skin. I instantly went to wash my hands with water but few of the glue stayed on my fingers along with the paper tissues I used to dry my hands. Yes I know there is instruction but, in a world that not many ppl read instructions, from the packaging the product appears to be one of those "easy for beginners." Threw this away right after this mass.
