That'd be superb, it's more how it's done. There's a thread on here with the process picture by picture but I can never quite get it. They always end up a tad misty no matter how much polish goes on them
Ok, I haven't seen that thread, could you link me to it please?
You will need a bucket of water and a sponge, I used warm water on dans as it was so bloody cold that day.
Some 1000, 1500 and 2000 grit wet and dry sandpaper, I just chuck the pieces I am going to use in the bucket at the start. As it turns out I was only able to find this sort of grit paper at Helfrauds.
Its a good idea to masking tape the surrounding body work before you start to sand.
Take the sponge and soak it in the water and wipe the headlight first to make it wet. Its best to keep wiping the headlight with the sponge every now and again so the headlight doesn't become dry.
Then I take the 1000 grit paper out of the water and rub the headlight side to side until the water running off is clear (not a funny yellow/green colour) and the surface feels smooth in that direction, this can take a little while as its such a fine grit. I also keep dipping the sandpaper into the water to make sure that is wet.
Then take the 1500 grit paper and do the same but go up and down instead of side to side. Make sure you did this until the surface feels relatively smooth from when you started.
The 2000 grit is the same processes as the 1000, side to side. Just make sure that both the paper and headlight are wet.
Now dry the headlight, its probably going to look really misty at this point.
You will need some Rubbing Compound, which you can get from B&Q and also Helfrauds. I used Carplan Rubbing Compound which I got from B&Q I believe.
Now once the headlight is dry you need to put the rubbing compound on to it and rub it around so it covers it all, I just use my fingers for this. Then I leave it a few minutes.
Now of this next part you are going to need something like this:

The one I have linked is the one I use. I did use one of them orbital ones from Helfrauds once and just didn't come out the same.
As most people know these sorts of polishers can cause damage to your car if you hold them in one spot for too long at a high rpm. I use this one at about half power and moved it around continuously.
Take off the rubbing compound with the polisher (very messy) until its is pretty much all gone, make sure not to hold the posher in one place for too long. After that you can give the headlight a rub with a clean cloth to get rid of any residue.
And then repeat the above process again with some plastic polisher, I used Meguiars Plast-RX.
After all that you are probably going to need to clean the front end of your car as the rubbing compound and plastic polisher go everywhere!
If you have any questions I'm sure you won't hesitate to ask
