Soda blasting will not remove rust. It is generally only used on vehicles which have very solid bodies but you want to get rid of the paint. It is very effective in that you do not even need to remove the windshield. Usually on something like an Amphi, media blasting is the way to go. It will remove the rust but does not have the heat and pitting issues associated with sand (sand is almost always a bad idea on sheetmetal).

Mixed opinions on lead filler. The instructors at McPherson's restoration program will tell you to get rid of it entirely and use modern sealers. Other purists will tell you that since lead is what they used at the factory then it is also what you should use today. Lead is certainly more toxic, more difficult to work with, and will cause you problems if not 100% prepped properly. You will have to do some work, do not expect that the original seam sealer will all be in good condition.

Subject: [amphicar-lovers] Soda blasting...

My car will be getting the soda blast treatment soon. I'm going to get
it back in a primer coat and address the fender rust and any other
issues I may find myself. My body man was asking if I would want to
inspect the body seams before they put in it primer. Is there a
factory sealer in the seams? Like a calking or something? I think I
read that the cars were lead seamed from the factory. I'm just
wondering if the soda blast might remove something from the seams that
should be reapplied prior to the primer.

Thanks...
