With water. In the age of the original absinthe fever, the drink was always diluted with water and sweetened with sugar before consumption. First, a cube of sugar was placed on a perforated spoon resting on the top of a glass of neat absinthe.
I had a minivan with paint on the hood and roof gone. The Maaco guys quoted ~$500 for their basic probably crappy paint on the whole car. I asked how much for the hood, he said $800 because he would have to match the paint and then apply clearcoat.
Using better materials and more involved preparation and finishing, a mid range car paint may cost anywhere between $1,000 and $5,000. It may also involve interior painting and areas near the engine getting re-colored. Typical warranties range from 2 to 5 years though may be more.
