'04 Navigator roof rack rust
My, new to me, Navigator came at a great discount because it had rust issues on both sides under the factory roof. Its is unusual to have rust thru cuz it's a San Diego car. Anyway, I cut out the rust spots back to clean metal n welded in new patch panels, ground it down. Then I put a skim coat of filler, primed n painted it. Now I'm ready to remount the rack, however I don't want water seeping in or leaching in through the sides of the rack mounts. The screws sealing issue is no problem. I got that covered. What would you recommend to seal the mounts to the body so no water gets in?
Thanks ahead of time for your input.

Do you mean water between the rack and the roof of the vehicle?
How did you seal the screws? Have you considered a fiberglass coating on the rack and/or the roof of the car?
A silicone sealant might also work well, I've read about that working well in similar situations.
Or maybe adding some nuts if you are confident of the screw installation to insure some space between the vehicle and the roof rack to reduce the chance of trapped water? That's probably not a good idea.
As I am sure you have, I have googled this for about the last 2 hours since you posted. Sorry if it's not helpful.
Based on all my research, if you've effectively filled and sealed the previous damage, you should be okay... my last suggestion is Rust Release Supergel .. but i don't know.
If youre not somewhere it's super humid, and you've sealed the existing damage I wouldn't be as concerned about future issues between the racks and the roof.
I could be super duper wrong. Just ideas to look into.

How 'bout using a Thule or Rhino roof rack instead of the factory one? Leave the cross bars off unless you're gonna use them. They're quick connect mounts. I never liked the factory roof rack anyway. No wind noise and a cleaner look.
