I had mine done while i worked for lexus,cost me £50 for the pack and £50 for the claner to do it on his day off,leather and paint work was done.I thought the leather treatment was sh**,the black was all dull and looked old,i had to use leather treatment and food to bring it back to what it was before it was done.The paint work was good.The cleaner washed then used a fine cutting compound then used the supa guard and pollished to a really good finnish,covers little marks and scratchs very well.All that said,it only lasted about 6 months and was not worth the money(and i paid £100).Its says it lasts 3 years,it is allso a protector for spills on the inside,not tried it though!!!!You can get much better and cheaper else were.
