Post Surface rust removal.

Whats the best stuff to use?

the entire underbody of the car has surface rust, (and alot of clay dirt) nothing has gone through yet and it is very minor. Would POR 15 be good enough? Im not looking on a perfect finish on the bottow heh, just something to kill the rust and seal the bottom of the car permanently.

I got that 66' Fairlane 4 door witrh 59k original miles. After talking to a few people ive decided to keep her stock, since shes a little rare. Plus shes totally complete, from all the trim, to the 4 ply spare tire hehe.

Clean it therougly with a brush and a good cleaner, spray POR-15's chemical stripper over the entire underside to get it down to the bare steel otherwise POR-15 won't work(Bare metal as in no undercoating or other coating, not clean steel, POR-15 needs the serface rust to adhere to). Clean it with POR-15's marine clean degreaser, spray the rust with POR-15's Metal Ready to nutralize the rust and coat it with zinc, then apply the POR-15 itself to seal the steel from the outside world and prevent rust from occuring again.

POR 15 directions say to clean loose surface rust with wire brush,Marine clean, acid etch with their metal prep and apply Por15, 2 coats. It dies smooth in abpout 5 hrs. and as hard as ceramic. Have been using it for years and no need to go to bare metal because it seals. Just get all loose stuff off. Por15 doesn't like bare steel (according to directions) it needs the rust to adhear good. Been using it on frames, underbody and I spray it into hard to reach places like inner doors with a Shultz bedliner gun.

I used this and it works GREAT. But you have to paint it or primer it fast.
