I am currently working on restoring 1949 Ford F3. I have the pickup stripped down to just the frame and have been using a grinder and wire brush to clean the rust off of the frame. I am not able to get into all of the areas with the grinder and have been debating if I should remove all the frame rivets and break the frame down to individual pieces so that I can get it really clean before I paint it. I would then get new rivets and use them to put the frame back together. My question is, is it really worth breaking the frame down this far or should I find another way to get into all the nooks and crannies in the frame? I am open to suggestions.
