I bought one of those kits once with the drill-based attachment for both sanding and polishing (can't remember who sold it) and I found it horribly ineffective.

The paper discs it came with were far too fine to remove much more than water-spots and the "polish" wasn't aggressive enough to remove the scratches from the paper included above. In-fact the first pics of my CRV lens shows the aftermath of that debacle from a year or so ago.

Your mileage may vary - I just didn't have the patience for it.

The most expensive part of this for me was the urethane at $19 at my local ACE hardware. I had everything else on-hand.

I agree with this. At sub $20 shipped on Amazon, you cannot go wrong. It works perfectly.

There are two 3m kits. One that you can do by hand, the other for an electric drill. I used the drill based kit.

There are several brand kits out there. Some much better than others. Many here have successfully used the 3M kit. The key is to work on a small area to completion and not use the course disk for very long. Spend much more time using the fine paper and polishing process.

I'm still looking for the best preservative treatment after you get them finished.

Depends what you want to spend. The urethane/min spirits mixture works well.

Or you can use Opti Lens.

I wish my headlights were repairable lol, some how the inside of the lens was affected as well as the outside...sanded the headlights so much I loosened up the headlight adjustment knob and it won't tighten/adjust now lol...shakey headlight FTL.

Oh I also plan on running my DIY seafoam kit through the brake booster line at the engine. I've been trying to remove most of the varnish and emulsified oil out of the engine and intake system...ran 7oz of seafoam in fresh oil 2wks ago, and it's already very very dark. So I know it's working :) cold starts are nice and quiet now too. Love seafoam.

So I guess a nice upgrade to Depo w/ AE's is coming up for you ? :thumbup:

that obvious eh ;) hahaha
