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:
“You will pardon some obscurities, for there are more secrets in my trade than in most men’s, and yet not voluntarily kept, but inseparable from its very nature. I would gladly tell all that I know about it, and never paint “No Admittance” on my gate.”
—Henry David Thoreau (1817–1862)
