Default Re: Headlight restore -- Blue Magic gets results

I have used the 3M Restore kit in the past with great results. This time I wanted to see what I could do without the kit. I wetsanded the assemblies on the bench. I started with 600, then 800, and then 1000. I found a small piece of 1200 so I went over them with it but not as much as I wanted. The 3M kit is mush faster because of the power tool involved.

Then I buffed them (polisher) with PlastX. Results were OK but not quite the 3M results. I rebuffed with Liquid Turtle Wax and now it was just as good as the 3M kit results.

Although these lights will look great on the car, on the bench in certain light you can still see some very very light scratching. I was reading some reviews and found this product called Blue Magic Headlight Lens Sealer. I picked up a bottle tonight at O'Riellys and gave it a try. I sprayed it on a rag and wiped the lens side to side very heavy. Then with a clean towel, I gently wiped it off. So far this product will get you back to as a new appearance as you can get. Tomorrow I plan to apply a few more coats.

If you have restored your lens recently, I would recommend trying this product. It will instantly improve the final results. Now to see how long it will last. If it needs reapplied later, it wouldn't take more than 5 minutes to complete.
If you can still see the scratches they will come back. As you know a brilliant polish is millions of microscopic scratches, even on a diamond.

As a cheap refinish to a headlight I used Brasso polish, it worked great for a month or so but I had only polished the tops of the defects and it did not take long for that to fail.

I learned that to finish Lexan Acrylic when making models of plastic drinking glasses and tumblers for customer approval the best obtainable finish was achieved by polishing extremely well and with the model in a lathe and spinning slowly run an acetylene torch over it at just the right distance, the minute scratches had the high points melted and the finish was like a mirror and you could see right through the solid model as if it was hollow inside.

I'm not too sure I would try that on a headlight unless I had a couple or three stiff drinks though.LOL

Finer and finer grits and lubrication is the secret, no short cuts. The finer the grit the longer that step will take.
