I'm hearing soda for paint but cannot verify it will remove rust? Would
walnut be better?
Thanks in advance.

Where is the rust?
I have both sand and soda blasting equipment and often use a wire cup brush on
a grinder. Depends on access. Soda is for paint removal, especially on
fiberglass. Soda is great for bringing dull aluminum back to a fresh cast look.
I also like phosphoric acid to simply dissolve the rust.
Sand is messy and reserved for an aggressive attack on a place that's hard to
get at.
Have no idea where I'd use walnut shells.
My first choice is always a wire brush on a grinder; least messy, quick, and
thorough.
