how much rust is too much?

I know if you can put a screw driver thru a body panel it needs work, but how about those deep pits , how much rust is too much? when should you replace or repair it? Will just a wire wheel and some good primer be enough?

to much rust ...well I tried to put an outside mirror in my truck and the bondo broke off wish there was some rust behind it..tried to grind off a bubble of rust on the door had to cover the hole with duck tape cuse now the rain runs through..every time someone slam's the passenger door I get a hand full on the running board..so the truck is getting lighter every bump!!...so to answer your question ..you never have to much it keep's twit's from leaning on your truck ,,you don't worry about your paint ..if you still have any..as long as the heater can make it warmer inside then it is out side ..your good to go ..

It will all depend on your skills or how deep your pockets are.
Generally, in the rust belt.....we look for better panels and install them. Don't forget, that in 60s and 70s and even 80s bondo was king, and these were just cheap work trucks. I bought replacement fenders from Mcphee Ford in Ohio and that was 1974....and I almost fell over when we got the price.....If the bondo and rust pits bother you...see a body shop and ask them some questions and pits to me are no big deal, but on a show truck they would be...

Generally rust is like cancer, it never truly goes away. To answer the question you must first decide the level of build that you are planning, then approach the rust accordingly. If you plan on a show truck you will want to remove all the rust, but if you want a nice daily driver then you can treat it with a converter which will last for several years..... If you can poke through the metal, it's gone and would need to be replaced. Heavy pitted metal that cannot be poked through can be treated, but you will need to temper your expectations on the longevity of the repair. Safety should be the number one concern, from carbon monoxide to generally keeping your feet warm and dry should top the list.
This of course is mho....good luck!!

No, any more than 7.84 lbs is too much. This has been established many times on the forum through rigorous examination.

Sorry,I thought it was understood that the Ford Rust Specification was to be regionally adjusted, i.e., Northeast, Rustbelt, etc..I stand corroded, I mean, corrected.

if its surface rust or just pitted a nice wire wheel and some good primer will do, i think.if its structural rust(if its going to make your front end fly on the freeway,i would be worried.)
Kevin had a thread of how to deal with the worst rust https://www.ford-trucks.com/forums/8...n-build-4.html



even if your truck is rusty,some A holes will still sit on your fenders trust me

On my door posts, they had a metal plate inside, near the bottom of the post, with the corners cut off and a hole in the center, to let water drain. But they get plugged with dirt. You can reach up with a wire from under the truck to clean it out.
