What does I-CAR say about blending clearcoat?

Response

Per I-CAR curriculum: "If blending the clearcoat:

  • be aware that this blend edge may not provide the proper UV protection and may deteriorate over time. Blending the clearcoat requires that the thickness of the clearcoat be reduced in the blend area. Generally, two mils of clearcoat is required for proper UV protection, and at the blend edge the thickness is near zero. This can result in the blend edge becoming visible after prolonged exposure to the weather or if the blend edge is polished too aggressively.
  • these types of repairs should be limited to lower, horizontal surfaces such as fenders, doors, lower quarter panels, and rocker panels where UV exposure is not as much of a factor.
  • it is likely not covered by the paint maker's warranty and definitely not covered by the vehicle maker's warranty. At least two paint makers offer clearcoat blending training. Glasurit offers a two-day Small-Damage Repair System training where technicians are taught how to use their twospray gun kit and spot blender product to do clearcoat blending. Provided these instructions, tools, and materials are used, BASF will provide a limited warranty on the repair. AkzoNobel has training on clearcoat blending as part of their certification training to help ensure that if clearcoat blending is done, it is done right. AkzoNobel does not provide a warranty for clearcoat blending, as it is nearly impossible to determine, at a later date, if the repair was done correctly."
