Ebay had the 3M kit on special about a year ago for about $12-$13, with free shipping so I posted a link to it, and several bought it. Now I think regular price is a little more $. It comes with the various pads you need, etc.. I first used just a 1000 and 2000 grit sandpaper wet and did it by hand. Then saw the 3M kit, bit haven't used it yet. Having just seen mhill's GLEAMING, CRYSTAL clear lens today (after he used the 3M kit), I'm goin' break it out and finish up mine. Especially on the top surface, near the horn.
Been 2 yrs now and still really clear on the front, I just have to do the crazing and cloudy top part. Mike's tip today was to be careful using the sanding pad at a 90 degree angle trying to get the side of the horns, as it ends up sanding/gouging the flat surface right next to the horn...
I'm NOT going to be trying the oven cleaner....
Start to finish...it's about 1 hr each lens, right around there.
