windshield pillar rust

After 351,000 miles (original owner) my 4Runner has its first rust spots on the windshield pillar. Unfortunately I have ZERO experience with body/paint work and it appears to be a little more significant than just surface rust. Anyone else experience this as well as tips to tackle this project? I greatly appreciate the help!

YOu can remove the rubber/plastic trim around the windshield. You then can clean around and apply some paint. I am not good in painting so cannot tell you on how to make it like new again.

For this reason, (using toyota's for the past 20 years and seen this), I use black silicone (gasket maker) and apply it between the rubber trim and the paint and between the glass and the trim, from the roof to all the way down to the bottom of the windows. This will prevent any water getting inside the trim.
 
I have the same thing on mine. Leave it for a while and you'll start getting water coming between the window and the metal! My solution so far has been to park it inside, but that's more of a short term thing. To fix this properly you're going to have to suck it up, pull the windshield and fix the rust. Hence my short term solution!

Have you gotten this fixed? How did you do it?
 
Bump.
Should I wait until spring to fix similar rust on the a-pillar? Mine is mostly on the bottom running into the fender, some on the top at 12-o-clock.

I have it fluid filmed for now, so in *theory* it should not spread dramatically until spring as it is parked outdoors in snow-ma-gedon.

I plan to get the windshield pulled (mobile windshield guy), grind off the rust, rustbullet or por15, rattle can, and get the mobile windshield guy to reinstall. This is all assuming I won't have massive holes to patch with welding or bondo..
 
Was the windshield ever replaced ? If so, probably a tool chipped the paint. Never fixed t. And yeah... that's why it rusted.
 
Mine's pretty bad too. Started leaking into the cab last fall. At first I thought it was a moonroof issue, but yeah.. turned out the water was coming in from the windshield frame. I slapped a bead of clear silicone caulking across the top where the molding meets the body, hasn't leaked since.

My windshield actually started to crack this summer, so I'm just gonna wait until next spring and bring it to a body shop for them to fix the windshield frame and replace the windshield itself.

If I have any rust that starts to form (none so far, fingers crossed), I will be following what this member has done to repair the rust on his 100 series Land Cruiser windshield frame.

Same here, I've already purchased the accessories for my Dremmel & the paints. I just ran out of time & warm weather to do it this year.

And scratches in the paint from shitty installers.

Shitty installers, this is what got mine.
It was all concealed by the (incorrect) windshield weatherstrip.
Three years ago, I slapped a bandaid across the top in the form of a 12" wide piece of flat black vinyl. It spans the entire width equally overlaping the roof and glass. Still keeps the water out even with 300+ days of CO sun beating on it.
Before applying, I used compressed air and a wire toothbrush to get as much loose stuff out from behind the weatherstrip. Then I applied some Eastwood Rust Converter. One day, one summer I'll dig out the glass and get to a legit fix.
Good news is my A pillars aren't rusty.
 
The trim, traps dirt, moisture and hastens rust. Ask me how I know.

My solution:
  1. Remove glass,
  2. Sand windshield mounting surface and surrounding down to bare, shiny metal,
  3. Apply POR-15 or other rust proofing and roughen surface to prep for glass install
  4. Reinstall glass with urethane (SIKA) adhesive directly on POR-15,
  5. Omit the trim, like I did, or use rubber which is better than chrome.
  6. Paint remaining exposed POR-15 to match body color, because POR-15 is not UV-resistant. (This step I have not done, yet).
 
Mine doesn't look like it has a trim. It's just river seal. The window does looked to be replaced by previous owner. Another reason could be like I said. When they removed the window they scratched the paint through. Years go by, water eats it away.

Rubber or chrome is still a trim.
Replaced glass or not, scratched paint or not, decades of moisture and dirt trapped under the trim will cause rust. Worse if you put watersports equipment dripping with saltwater. That's why I eliminated the trim on mine. No chrome trim, no rubber trim. That's just cosmetic part that causes problems.
