Has any one addressed the rusty sun roof frame parts, mine has severe rust on the cross piece at the front of the slider on the inside, on another car I was able to remove the entire slider and sandblast the area and prime/paint, but I caught it before it was terrible. I have not tried to remove this slider yet, just wondering if it is worth trying to repair or better to replace. I expect a boneyard replacement would possibly have the same symptoms, but if anyone knows of a good replacement frame cheap, I might go that route.
