         11 . The paint film applique of  claim 1 , comprising the topcoat layer. 
     
     
         12 . The paint film applique of  claim 11 , wherein the topcoat layer is polyurethane-based. 
     
     
         13 . The paint film applique of  claim 1 , wherein the in-situ polymerized carrier layer has a peak loss factor of at least about 0.5 when tested as a standalone film according to the Loss Factor Test Method described herein. 
     
     
         14 . The paint film applique of  claim 1 , wherein the in-situ polymerized carrier layer has a peak loss factor that occurs at about a temperature of at least about 35° C. when tested as a standalone film according to the Loss Factor Test Method described herein. 
     
     
         15 . The paint film applique of  claim 1 , wherein half-height loss factors of the in-situ polymerized carrier layer occur across a temperature span of less than about 40° C. when tested as a standalone film according to the Loss Factor Test Method described herein. 
     
     
         16 . The paint film applique of  claim 1 , wherein the adhesive layer is present and comprises a pressure-sensitive adhesive. 
     
     
         17 . The paint film applique of  claim 16 , further comprising a release film on an exterior surface of the adhesive layer. 
     
     
         18 . The paint film applique of  claim 1 , wherein overall thickness of the paint film applique is less than about 130 microns thick.
