YES !! Other than B7 , B8 , F8 and X9 (any others ?) , the blackout on the core support is *supposed* to be there ( yes , I've seen cases where there was little if any , on 100% original cars in the salvage yards ).
This is especially necessary if the car's colour is Hi-Impact , yellow(s) or red(s) . And , no I don't mean Quaaludes (yellows) and Lilly F-40's (reds) :D
