Bests & Worsts Reviews from Amazon

I am the type of buyer who does a lot of research before pulling the trigger on a purchase and the case of buying a headlight restoration kit was no exception. Now that I have bought and used this kit, a few helpful hints: - On Amazon, there were three 3M kits listed, the 39008, the 39014, and 39045 for approx $17, $18, and $24 respectively, all with great reviews. I couldn't for the life of me figure out the difference int he kits, so I went with the cheapest, the 3M 39008 Headlight Lens Restoration System. Well, now I know the difference. ALL the kits include: 1 - 3M drill backing plate 4 - P800 grit white abrasive discs 6 - P500 grit yellow discs 1 - P3000 Trizact foam disc 1 - Orange foam compounding pad 1 - 1 oz. 3M headlight lens polish sample - The 3M 39014 Lens Renewal Kit includes all the above plus: 1 - 3M Masking Tape PN 0000 25 ft. - The 3M 39045 Lens Renewal Kit with Protectant includes all of the above plus: 1 - Container of protectant formula I had making tape, so no biggie there, and I just used a high quality automotive wax on the lenses when I was done, so I didn't need the 3M "Protectant formula". You also provide a 1200-1600rpm drill (use a corded drill, cordless just won't cut it, you will run out of charge in short order) and a pray bottle with plain water. Maybe my lights were particularly bad, but it took me a good 1.5 - 2 hours PER lens to get the results I did. But I am a perfectionist, and took my time. I would say the lights came out at 99-100% I'm not sure what those who wrote negative reviews were doing wrong, but if you follow the directions and take your time, the results are great. Some tips: - On the first step with the P500 grit. Clean the lens and the disc OFTEN. A old towel works well for the lens and a paint brush worked well on the disc. By cleaning the disc often, I was able to do both light with just a single P500 disc. If you rush, you WILL clog up the disc and need a new one. This is the most time consuming step, took me about a hour a lens. - On the P800 disc, same as above, clean the disc and the lens often! - With the 3000 wet disc. Keep the pad and the lens wet, wipe the lens often! (Noticing a pattern?) - On the polish step, just a little compound goes a long way! Just a dime amount on the pad will do you just fine. - Finish up with a nice high quality wax on the lens to protect your work! If you take you time and follow the directions, you will be very happy with the results. For $20, and 4 hours of my time, I was very happy. Much better that the $180ea for new lenses!
