Thats what I was afraid of. You guys confirmed it's going to be a nasty messy job.
It's old primer, I don't really trust putting a nice paint job on top of it. It's been weathered a bit and has kinda a white powdery film to it. You get a thin layer of white on your finger when you wipe it. So I doubt I would want to put a 6k paint job on top of that.
