Hi, I recently rented a steam pressure washer to clean the undercarriage/bottom of my 78 Solar Gold TA before installing new exhaust and suspension. I removed 45 years worth of old dried caked on oil, transmission fluid, grease grim etc. taking it back down to clean bare metal in most places. There are some areas which still have what looks like a reddish zinc Oxide type paint on the floor panels. I've owned the car 38 yrs. My car is 99% factory and I would like to keep it that way. My question is was the chassis, frame, and floor panels originally painted/coated under there or was it originally bare metal? Ames says it had the zinc oxide coating which make sense as there is still some left. Classic Industries says it was all painted black which I know is false. I asked the tech rep why there wasn't any black paint left and hew said because my care i old? Sorry for the long rambling post lol, Charlie
