Acid dip experience???

My motivation is paint/rust removal, not weight reduction. I can note any sealer beforehand in addition to the shop manual which shows a lot (all?) of the sealer locations. I've read in some cases where you're still finding soda residue with the paint gun. However, I've never done any of these and I'm relying on your experience. Whatever I do will be done in the Indianapolis area. After I remove the tail light and bezel I have a sheet metal structure(s) spot welded to the quarter. I will replace the quarters later and would like to replace this structure on one side. Acid is out. What can I reasonably expect to pay for media blasting? I want to get rid of the paint, rust, crud so I can find out what I'm working with.
