I just noticed my excursion is rusting at the bottom of all 4 door panels With the rubber seals you wouldn't notice it unless you look for it
I was thinking of using pro-15 metal prep before the por-15, anybody used this
and how did it work? Thanks Rusting away in Mn, Curt;
@Snowseeker did a write up on that exact thing a couple of years ago, I'm pretty sure that he did use POR-15 after a good cleanup of the area.
Now you made me want to get home and check mine in the morning.....
Its under that weather stirping where you wouldn't normally wouldn't check/look at
Been there, done that, got the T shirt
Thats the first place to look for rust followed by the rocker panels. I removed all the loose stuff, went over it with por 15. Look for loose stuff you might miss after Por 15, remove, apply another coat. I then primed and rattle can painted it. You don't have to do the paint since no one will see it. If its from the north, the right side is usally the worst--I suppose becuse they plow all the salt laced snow to the right side of the road.
Friends of ours have a body shop and have done some of these repairs on another customer's Excursion. They say it's the lack of good drains in the doors that allows water to sit there.
This winter, I pulled all 4 door panels and sprayed Fluid Film into the bottom of each door to help prevent this. If doing a rust repair, I'd suggest getting some sort of convertor, etc into the bottom of the doors as well as the outside.

I can't think of the proper name but the base of the door frame (which I errantly called the rocker panel)underneath looks somewhat like a gutter. It has the poor drainage issue as well--making it high on the rust list. Some people have drilled additional holes. On my 05 I found a hole which rusted through from underneath
I also did a write up on that with pics about 5 years ago. I ground off all the rust and POR 15'd all 4 doors. I also put it in very heavy inside the door. They haven't popped since.
Yup. First year I had my X I went threw the doors. The drivers side was the worst, the rear doors I just filled with oil as they didn't have any rust starting yet.
You should scrape out any loose rust. I got to the point where I pryed (what was left) the pinch weld apart to dig the rust out. I also pulled the door panel and scraped out the rust on the inside and all. Then I por-15 the inside and out and inside of the pinch weld. While the por was still wet I crimped the pinch weld back together to trap the por inside as well as use it as the bond between the two panels. Once again I por'ed over the whole deal, then after it was dry a white coat to color match.
The drains aren't much of a problem, it is the salt and fords lack of metal coating.
did some doors recently that were rusting and while the outside seem was realitively easy to wire brush the rust off and coat, the inside of the door and seam was the real concern.
I ended up making a oxalic acid paste and coated the inside of the door. the paste oozes into the seams and nooks and crannies. I let it sit over night and then used a shop vac to clean out the door.
the acid completely removed all the rust but to neutralize the acid i drilled 2 small drain holes in the bottom of the doors then flushed the inside of the door with fresh water.
I used a leaf blower to completely dry the inside of the door. then let that side overnight.
to prevent further corrision I used a cold galvinezed coating from rusleoleum.
regardless of what products you use, first neutralized the corrosion inside and out, then coat the area to prevent future corrosion.
With the rubber seals you wouldn't notice it unless you look for it
