Protection against impact damage to delicate items stored in a protective encasement such as cell phone cases is significantly improved by protectively lining the interior of a protective encasement with a unique protective combination. This combination includes a protective inlay or insert of a thermoset viscoelastomeric protector in its static form coated with a compatible and non-confining elastomeric polymer coating. Coating the viscoelastomeric protector with the elastomeric coating necessarily requires retention of an undistorted viscoelastomeric protector in its static form during the formative coating procedure. This can be effectively accomplished by injecting coating under low pressure and high solids coating conditions.
