Hi all. Just purchased a 07 Voodoo Blue FJ in Chicago. Drove it down to Nashville and am having a blast. The FJ has a little over 100k miles and it is in great mechanical condition (checked by Toyota and a local mechanic). Excited to take it on a few trips and hopefully learn how to go off-road around here. The FJ has some surface rust, nothing structural, that I would love to address. I've been calling around but it looks like not a whole lot of folks in Nashville have experience with surface rust, any recommendations on what is the best way to slow the spread of surface rust?
