I bought the better of the two 3m kits, it came with the polish. It was very easy and worked incredibly well. It has been 3 months and they still look great.
Driving visibility has been greatly improved after installing the Boslla B4 led headlight bulbs. They have 6500k/4300k/3000k three color temperatures, work perfectly for rainy, snowy, foggy, and more extreme weather conditions.
