I called Randy at NW Ice Blasters 503-680-0816 http://www.nwiceblasters.com/ to get a quote on blasting clean the 51 fuselage, for that matter, all the parts. Well it turns out that the most expensive thing are the ice pellets. So he offered to come out and give it a try for a few minutes so we could estimate the time it would take, my guess is that it would be $1000 at least to do the whole fuselage. The top is the easy part, doing the bottom of the structure, this would save a ton of time and money and it does no damage at all. I would like to try it on the engine before I take it apart.
