I am restoring a 71 chevelle and have a question about the underbody color. After cleaning I found that the majority of the floor pan area, inside and out is still covered in the original reddish brown color. this car is from Alabama and has never been undercoated and rust is almost non exsistant. This looks like red oxide primer but has a semi gloss appearance. Also it seems to be a thicker coating than primer. Does anyone know what this is or can you point me to a product that will match this as I don’t want to do what everyone else has done and just paint it black. Thanks
