A paint sealant is a sealant that protects cars from ultraviolet rays and acid rain. Paint sealants protect cars' finishes, and can make cars shiny. There are synthetic sealants and carnauba waxes.
Salt may be a factor that many protective sealants do not defend against, and thus salt water may break down protective layers to get at the metal and corrode it.
Famous quotes containing the word paint:
“... to paint with oil paints for the first time ... is like trying to make something exquisitely accurate and microscopically clear out of mud pies with boxing gloves on.”
—Brenda Ueland (1891–1985)
