Fluid Film has to be applied once or twice a year. Safe for bolts/nuts, but not for pure rubber seals over a long period of time. You need to read the contents. It also stinks according to someone I've heard from, at least if you do it inside.
POR-15 is a one time application, but you need to degrease, metal prep (phosphorus coating - etches the metal), apply two coats and spray over anything that's exposed to UV light with a top coat. Also, don't get it on the threads or underneath any of the nuts/bolts; it sticks like glue. You should also wear a mask if you plan on doing the entire frame.
I did my entire truck in POR-15 after it was covered in surface rust. Had to wirebrush everything and wear a shower cap to avoid getting the crap in my hair. If you get it on your skin, you need to clean it off immediately or you'll be waiting two weeks for the dead skin cells to flake it off.
Just my two cents.
