The LA factory cars were not undercoated in the front (in all examples I've seen) but they did have varying degrees of sprayed on black out paint applied to hide the body color from showing when veiwed from the sides of the car. The sloppy application looked backyard but that's how they looked, fast and sloppy. All indications I've seen point towards the same guy who blacked out the radiator core support area also did the forward wheel wells. Don't lose sight of the fact that YOUR car is it's own blueprint for getting the details right, rely on all those predissasembly pictures you took that I ragged you about early on
