The corner has been turned as I have gotten my 53 B4C frame cleaned and painted. My friend decided to have a car sandblasted and offered to have my frame done at his shop at the same time. The mobile sandblaster actually used a dustless system with glass and it made the metal actually sparkle. After cleaning I found a cross member had some hidden rust damage so it was removed, patched and will be bolted back on. I then painted por-15 and am really happy with the results. When I get it back to my garage I can actually start putting parts back on instead of taking them off!
Here are some pics of the frame from dirty to clean to painted. (by the way for you sharp eyed people, some repair work was done on the frame in the past as the driver's side running board supports had the rivets removed and replace with bolts - they will be put back on later along with the cab supports and cross members you see missing in the pictures)
