Right then, heres a quick picture of the headlights. both of them were pretty much in this state. not brilliant tbh, loads of small scuffs and scrapes that the rubbing compound simply wouldnt get out.
Started on the offside by taping it up properly. used loads of masking tape. I would suggest if anyone else uses this kit to mask off a large area and put a layer of gaffer tape over the top of it as I caught the masking tape with the edge of the buffer and it whipped it straight off, lucky it wasn't an abrasive pad.
first sanding pad which is the course one of the two.
Then move onto the second sanding pad which is much finer.
Then after wetting the light and removing all of the dust, you use the abrasive sponge for around 5-10 passes, it removes pretty much all of the scratches and swirls from the abrasive pads, because its wet, it creates a slurry when you use it which is why I didnt grab a picture.
moving onto the buffing sponge, you dry any excess slurry from the light and put the supplied rubbing compound onto the sponge. using the sponge to smear it all over the front of the headlight to avoid it splatting everywhere
I didn't read the instructions like a moron and it went everywhere...
After a few passes of working the compound into the light, it looked like this...
and the nearside unit
to protect the light and my hard work, I used Auto Glym resin polish on the lights followed by two coats of Collonite wax.
In all, the job took about 45 minutes to complete. I have enough spare parts in the kit to potentially do the lights another few times if required but I will be keeping a close eye on them to see if the scuffs and brown/yellowness come back.
for the cost of £20 and a bit of polish and wax, I cant really fault this kit from 3M. easy to use and didnt take that long to get a near new result which I am really happy with.
