So I spent some time this Sunday morning doing undercarriage cleanup using a degreaser called Purple Power, works really well, almost too well. It took paint off in some places. What I noticed near the back of the vehicle it appeared to have original gray paint on the underside of the tub. This is an area where a PO had a long range aux tank installed and so I figure that area was quite undisturbed. Other areas under font fenders show red paint that appears original and some black undercoating AND that gray color. So this is a question for all the experts. We’re the areas under the body and fenders painted gray from the factory or stock color? In my case Freeborn Red. And was black undercoating added at the factory or just a PO’s addition later? Thanks any info appreciated. Below are some pics some under tub, some under fenders. Thanks guys.
