Got the headlights on my 15 yo Mazda 6 restored today through Baz at Headlight Restoration Adelaide.
Would highly recommend to anyone, he's a great bloke. He comes to your place (fitted me in within 24 hours).
Did a top notch job and turned my dull, yellow, cloudy headlights into looking brand new with a life time guarantee.
If you're looking at giving your car a bit of a spruce up I highly recommend getting this done!
Had tried it myself after buying a $40 plus kit but it was absolutely rubbish.
