I can see clearly now, the haze is gone...
OK, I cheated! I have now restored 3 cars with this one kit and still have more supplies left to do more. OK, I have polished Plexiglas before, aircraft mostly and have a few hundred hours under my belt hand polishing plexi by hand so I had a slight advantage. Here is how I use these kits. First, the aggressive disk? I run my 220 grit DMT over it to knock down all the large grit and make it smooth. Then I use a spray bottle with warm but not hot water with 2 drops of liquid dish soap, Dawn works very well. I dip the disk into a bucket of fresh water and start removing the oxidization with the coarse pad at continuously spray water on the light as I work the pad around in coffee cup size circles. Once there is a good amount of white gunk dripping off the light, I wipe the light off and dip the pad into fresh water, then repeat the process until the whole lens is white but has no deep scratches. Repeat the process with the next two disks, keeping in mind that if you push the pad into the lens, it will gunk up and that pad is shot! Slow speeds, light pressure, lost of water, NO gunking up the pad. All of the pads with the exception of the first pad are all about removing the scratches the first pad made but if you don't get all the way through the milky white oxidization layer with the first pad, you won't have clear lenses when you are done. Once you get to the sponge and the polish, keep in mind that if the polish to thick or drys out, you will burn the lens. Use as little (BB size dab) of the polish (buffing compound) as you can and keep the sponge moving! DO NOT use pressure, let the sponge do the work. Yes, it will take time, be patient. Good luck, ask questions if you like.
