I love to talk about paint vs. patina. My truck sat in the brutal hot desert sun in southern Arizona for 25 years or so. Luckily, somebody had slapped a cheap coat of paint over the original before parking it. When I dragged it home and served eviction notice on the pack rats and scorpions I took a pile of 600 grit wet/dry paper and a Homer bucket of water and over the course of the next couple of months, "unpainted" it. It could use more work, but I sure like the results so far..
