Headlight restoration job on a 2003 Porsche 911.
The owner of the vehicle had be told by the previous owner that someone tried restoring the headlights themselves and as you can see failed! A yellow residue formed on the headlights due to this. Most likely caused by using incorrect products.
At Crystalline we only use professional products/compound, which as can see has completely removed the yellow marks/residue and made these headlights look new again!
