Great work! I sure wish my '54 was past the demo stage. There is a Redi-Strip just North of me in Canada where they can dunk the whole body, strip the paint, and remove the rust with electrolytic process. Final treatment is phosphoric acid etch I believe. Have not got a quote from them yet.
I finally scored the rear sill piece I needed. Mine was toast. I would like to galvanize that piece! Have you kept up with Ray the Metal Man? He has done a lot to help us. Has his own forum over at Oldgmctrucks.com. The photos are really great.
