i've used the urethane on two vehicles (I am a hobbyist). I thought it laid down better than dupont centari (the only other auto paint I have ever used) and I have read that it is simply relabelled PPG Omni (I have no way to confirm that - I've just seen it posted in other forums).
One note of caution - I was very disappointed with their "factory match" color for a vw i was spraying. I would not recommend buying this paint for a factory correct style project where you want the color to be very accurate.
urethane paints are more like plastic than acrylic enamal. They are marketed as being more durable (UV resistance, chemical resistance and abrasion resistance). I think it's true, but only because I tend to believe manufacturer's claims and they all claim this.
