I must say I came away very impressed and satisfied with this product. I first looked into just going and buying some sandpaper and polish but could not find any multi-packs or single sheets at our local hardware stores. I did not feel like spending $4 a pop for each level of grit.
So, I opted for this $20 kit (http://www.crystalviewchemicals.com/myheadlight
) at Advance Auto Parts which included 2 pieces each 1000 and 2500 grit sandpaper in the package. I probably could have used a courser grit such as 800 or even 600 as it took so much longer to wet sand everything. The 2500 was really nice as it smoothed the surface out quite nicely.
The package sells the idea of a "5-minute" job.....well, unless your headlights are just slightly hazy, don't count on it. I spent near two hours total between the two headlights, of course there was the dis-assembly and reassembly time of taking them off the car.
As it was getting to be dusk, I was able to get one shot of a comparison between the sightly yellowish hazy headlight still on the car and the one I had just put a first layer of polish on.
I know there are many products like this one out there, but I would highly recommend it for ease of use and the finished product it delivers so long as you are not dealing with a lamp that is pitted very heavily. At that point I would just suggest adding some coarse sandpaper to wet sand before using the 1000 grit included in the kit.
Just my 2¢!
