I'm very glad that I chose to blast these reproductions down to bare metal. As I blasted tonight, there were areas that flaked off well before the media got close, there were areas with grease streaks from the stamping under them, areas with fingerprints, slightly rusty areas, and some areas that I couldn't figure out. Not what one would want to base a paint job on. I've heard some people have never had a problem, but from what I've seen here...yeesh. I wouldn't.
I'm not quite done. We ran out of buckets of sand and had to refill them, it was late, had to 180° the box to finish up the end pieces, so we shut it down for the night.
