A NOTE ABOUT UNCOATED HEDMANS:
Hedman offers these uncoated hedder for vehicle owners who wish to apply their own type or color of coating. The Black paint applied to them at the factory is merely to protect the bare metal from corrosion while in inventory and during shipping. This coating is not a high temperature paint and will burn off after only a few minutes of use on a warmed engine. Although an uncoated hedder can be used, we recommend the use of a thermal coating, or high temp paint to protect them from the elements, and prolong their life. ALL uncoated Hedman Hedders are available with HTC Ceramic-Metallic thermal protection, and is factory backed for 5 full years.
Contrary to popular belief, the use of a thermal wrap on hedders will cause crystallization of the steel tubes and actually dramatically shorten the life of the hedder. The use of hedder wrap is so detrimental to the integrity of the hedder, its use will void your hedders lifetime warranty.
