 Because we must take into account the loss of energy caused by the addition of the clear coat layer, we can reformulate the BRDF from equation $\ref{brdf}$ thusly:
 
 $$\begin{equation}
-f(v,l)=\fDiffuse(n,l) (1 - F_c) + \fSpecular(n,l) (1 - F_c) + f_c(n,l)
+f(v,l)=\fDiffuse(v,l) (1 - F_c) + \fSpecular(v,l) (1 - F_c) + f_c(v,l)

 Where $F_c$ is the Fresnel term of the clear coat BRDF and $f_c$ the clear coat BRDF
