Fluid film rust treatment

What are your thoughts on it. I should have done something to my 2006 Dodge 3/4 ton several years ago but I didn’t so I’m kicking around doing something now before it’s to late. It’s pretty good underneath but I have some body rust needing addressed. I can do some body work but in Pa if I don’t do something soon I’ll be Fred Flintstone yaba daba doooo.
