Just washed my truck, found something new.

The bottoms of both my doors are rusting out. :(

I noticed it as I was drying the underside of the door, the shop towel was orange. It wasn’t like that last time I washed it.

My first instinct is to do nothing and just leave it as is. I suppose I could sand it down and put some rust converter on, but that won't do anything about the rust inside the door panel.

Remove the doors, become a Jeep.

I would not say they are rusting out because the metal looks good . I would say that they are rusting from the metal edges and if you leave them un treated they will bubble around to the outside and ultimately rust out.

My ‘07 chevy uplander had the same issue. I discovered it when washing and I fixed it “good enough” in the same afternoon.

The method was easy. CLean up the rust with a wire wheel on a drill or dremel. Hit it with automotive rattle can primer and then finish paint it with a rattle can. Clean up the rust, seal the edges and it will be fixed. I didn’t even tape anything, 

Must uplanders of my generation are rusting at the door bottom except for mine. In fact it’s probably been 4 years since I painted it.

Yup, sounds about right for a Ford. My FiST had rusty door sills after just 3 years.

I’m guessing you live in an area where they salt the roads?  Do they use rock sa lt or the crazy gnarly magnesium chloride?

Potash salt covered in liquid magnesium chloride. The city also uses sand.

Ya I should probably fix it.

My Mazda started doing that a couple of years ago, the sanding and repainting only lasted for one year and the rust is back.

sounds like a recipe for rust. you might do as other have suggested and hit the rust with a wire-wheel and then mask and paint with a protecta nt p aint or maybe rhino liner, as long as it’s concealed well.

go0 d  luck!

Block off one of the drain hole and give a good squirt of rust inhibitor into the other hole. Water must be collecting inside longer than it should.

Also give you window rubbers a good clean. Wind down the windows then with a small brush or rag wrapped around your finger use an anti bacterial cleaner, then wipe with alcohol then allow to dry then apply some rubber trim restorer to the exterior of the rubber to make it more supple again.

David Tracy would kindly disagree with you, that would barely qualify in his book (or yard).

At least one plus to removable panels rusting is you could always look for doors in the same color that are rust free...

I feel you though - I just noticed some more rust on my car just behind the front mud flaps ...looks like only surface rust now, but I DROWNED it in Fluid Film for the time being and will book an appointment at the local autobody place to get an estimate when I can soon...

There are also two huge dents in my passenger-side rocker that I don’t remember being there....looks almost like somebody hopped a curb with it, but I don’t ever remember doing anything of the sort while I’ve been driving it unless it was the last sketchy garage I had taken it to ! :(

The perfect is the enemy of the good. Hit it with a wire wheel then primer and then paint twi ce and you will never have to see the rust going around the corner.You are l ucky having only 2 doors, I have 5,.

If you don’t do it now, it will be blistering up the outside in a year........
