The UV Visualizer Training Kit comes with everything you need to become an expert in UV Curing. The kit gives you the step by step instructions to take you from novice to professional in 30 minutes or less. This simple but very effective kit allows you to practice your curing technique over patented UV reactive color strips. As you pass over the strips with the handheld curing device, you can visually see the color change in realtime. This gives you the immediate feedback so you know if you're going too fast or too slow or keeping the device to far or too near to the vehicle. The beauty is that by learning on UV reactive paper, you don't need to learn on an actual automobile.
