Tips and warnings

  • Do not use a metal putty knife in place of a plastic one as this may scratch and scar the underlying surface.
  • Do not mistake turpentine for lacquer thinner, a much harsher solvent.
  • Do not use an unbuffered plastic putty knife to scrape over-spray away from wood, plastic, fibreglass, or vinyl or you may scratch and scar the underlying surface.
