Under Body Color

Q: Under Body Color

Do cars come black underneath, or painted? All my vehicles are body color underneath, w/ stuff bolted to it. Under the body paint there is black paint followed by bare metal. Why would they take the time to mask it and paint it black, when there’s someone under there w/ body color already in the gun.

A: The body shells were painted before assembly, and the overspray was so heavy you would believe they intended to paint the whole bottom. Maybe some were heavier than others, but all I have seen were still only covered enough to be considered overspray. As you rub on it with steel wool or 400 wet sandpaper, you will see it comes off like overspray even though the color is fairly vivid, leaving the solidly applied black.

A: theres a more logical explanation to all of this. OVERSPRAY. It is red because your car was red. It wont have the same gloss,color or texture as the upper body parts because it was never intended to be painted body color. Overspray will be evident even upwards into the transmission tunnel altho it probably wont reach the middle of it. I have a Meridian turquoise and 2 solar red 68s that have the same overspray patterns on the underside. The meridian turquoise one was Ziebarted (Paraffin based under coating that looks like beeswax) when new, which perfectly preserved the whole under side of the car. There is no evidence of any red primer on any 68s Ive ever had or worked on. Look under the gas tank as this is usually shielded from most of the harsh elements. You will find the same red overspray there.
