Painting Instructions

  • Two year limited against manufacturing defects or inner structure failure. Warranty covers hood only.
  • Supplier identification number will be inside each hood for warranty administration.
  • Because of the nature of open molded fiberglass Jones Performance cannot warranty gel-coat cracks. This is also known as starburst or spider cracking. Our experience has shown us that forklifts are generally the biggest culprits, it should be noted, if the forklift forks do not go all the way through the hood (rear to front) do not use forklift to move hood.
  • Guarantee hood to fit
