i tinted my tail lights a year and a half ago i used about half a can for both tail lights and mine are as dark as can be. they still have a great shine with only half a can of Clear Coat. I did my head lights also but at night it doesnt look right. i turned of the DRLs so during the day my car is blacked out. but at night it shows up purple blue and shows the lines even though it looks perfect. this is the best way to go though. Below are front and back but used from just one can of VHT and one can Clear Coat
