Securing loose ext. A-pillar trim?

[SedonaBound]

The exterior A-pillar plastic trim has a 1/4 gap where it curves around the windshield and makes a lot of noise over 50 MPH. Any suggestions on how to best secure it so its flat & snug and won't lift from air pressure? It's not really loose; more like the plastic trim was molded with a bias against staying flat. I was going to try 3M double-sided tape between it and the end of the horizontal trim it overlaps.

I have tried a bunch of things like rtv.. epoxy.. stuff like that and then used some foam weatherstripping stuff with that epoxy.

None of that worked. I still have the noise and now I have a mess of an a pillar trim. :shame:

I think a mechanical method (screws for example)

Get a lightbar, it should stop the wind noise from the pillar.

That same black gunk that they used to hold down our fake hood louvre. Worked like a charm.

Did you put only where the plastic parts overlap, or did you put it on the glass too?

Just plastic overlap. Hasn't budged since, and it's been over two years since I did it. Mine was way worse than yours too.

I drilled a hole and placed a riv-nut in the metal A pillar, then secured the plastic trim with a stainless button head. I did that about five years ago. No more issues.
