I saw at canadian tire near the paint section this one spray which claims that if you spray it on rust, it will turn the rust to healthy metal. I figure if it was so true, wouldn’t everyone be using it… I didn’t get it but I contemplated about it, although to be honest I find that retarded, I rather sand down and paint over properly. Anyone have experience with this kind of stuff? I forget what it’s called, it’s at crappy tire.
Try that man… it’s probably cheaper 
POR-15!!! lol!
