It is a polyurethane set up for insurance work but lots of flex to 4 inches thick and gets to hardness faster than universal.
Guess you could call it medium-hard.
Euro sprays and lays out really nice. Probably the most user friendly (haven't used the speed clear) of all the SPI clears. This Subie WRX was one I did with Euro. Collision repair. Hood, fenders, bumper cover (off the car) and base blend into the front doors. Doors were fully cleared. No buffing.
