Headlight restoration w/Meguiars professional kit

[MNDSMtuner96]

Hey guys. I just purchased the Meguiars Professional Headlight and Spot Repair Kit and just have a few questions. I have searched and searched for these answers and have had no luck so hoping a few of you that have this kit could help me out. First off, I am new to the whole sanding thing and haven't wetsanded paint yet either but cant wait to learn and perfect this art. A couple years back I purchased the Diamonite headlight kit and while it works it obviously does not compare to sanding. So my questions are;
1. What speed do I run the tools at? Full speed?
2. How do I know what grit to start at?
3. How does this compare to hand sanding the headlights?
4. Why are there only 15 1000 and 3000 grit discs? Do they hopefully last longer so you dont have to buy them as often?
Im a total noob when it comes to HLR but really want to incorporate this service into my business. Thanks in advance!!

Thank you for sharing, but I have seen these videos and they don't really answer my questions.

1. Haven't used the pneumatic ones so I can't say what speed. On and electric DA I would say speed 4-5 small GG 3" DA speed 6

2. Most headlights you want to start at a lower grit. You want to ensure your remove all of the faded lens and plastic then slowly refine your sanding marks with a higher grit.

3. There are some similarities in that your want to remove equal amounts of the lens with both techniques however the machine way is much faster and allows the removal to be much more uniform.

4. These sanding discs do not last forever and will need to be replaced. The give you enough to get started but you will have to buy more.

Thanks again for your input. I know the discs dont last forever I was just wondering if the finer grit ones last longer? Cause you only get 15 compared to the more coarse ones that you get 50 of.

The finer grits do last longer but nothing too noticeable.

I just watch a youtube vid from 2010 that a Maguiars rep was showing this new product (Headlight and spot repair kit) At SEMA? I think he stated that you use more of the courser grits (2 or 3 per lense) that is why they give you more of them in the kit. The finer grits last 5 or 6 lenses.

What polisher is being used in the second video?

Certainly looks like a porter cable with a small backing plate.
