Take your time though, cause when using this kit and a drill the sandpaper disc can get clogged and put plastic back on the lens so check the disc after each pass. When you get to the wet sand phase make sure to take 3-4 passes. On the polish phase just use a dime size of product cause that sh1t will sling everywhere. Oh and on the wet sand phase use a spray bottle with one drop of dish soap, it helps with the buffing. I have done 18 sets of headlights and had awesome results every time with the kit.
