On my B body, I pressure washed out the channel around my windshield, and rear window, with the trim off, and was left with what seems like factory sealer or putty of some kind.

What's the best way to encapsulate, or reseal this gap/seam? Was contemplating masking it off and using some kill rust in there.

I eventually have to reinstall the trim and clips for that.

Thoughts?

Lord Fusor is about the best seam sealer there is. It's flowable and gets into the little cracks really well. It ain't cheap, but it's very good.

Thanks, I will have to look that up. Wanted something that would not trap water long term. Car won't see much rain, and doesn't seem to leak now, but better safe than sorry, especially with knowing rust can hide anywhere

That tagged as a seam sealer, or a windshield adhesive?
 
Windshield adhesive is what should be used there, not seam sealer.

It appeared to me he was talking about the metal seam in the windshield channel. If he is, he needs seam sealer.

Maybe it was. Most of what’s in the picture is old dried up windshield adhesive though. And if he wants to replace the seam sealer that is there around and under the windshield adhesive, then the windshield will have to come out along with the old adhesive
 
NO NO NO. I Agree Fusor products are the bomb but... that glass need to be pulled for a proper repair and then accessed from there. If I was looking for a cheap patch that would not cause extra work for a proper repair, I would pound that full of butyl ribbon and hope for the best.

I'll build ya a bullet proof glass adhesion for a short block stroker. LOL
 
Thanks all, top picture is the front. Bottom picture is the rear. The rear has that extra layer in it of some kind of putty. Not sure if it's factory or not. And not sure the best product to to use, that's why i asked.
 
What year B body. This appears to be a 71 or newer. The glass on those is glued in with urethane adhesive. 68-70 charger rear glass is glued in as well

To do this the right way, you need to pull the glass, strip all the rust out of the frame, epoxy primer and paint the window frames, install new moulding clips, then glue the glass back in with urethane windshield glue. Otherwise all your doing is a bandaid fix. Regardless of it being in a dry condition, used only on nice days etc, your still going to wash the car, water is still going to lay in these areas at least till it dries. If the windshield has flaws, now would be the time to glue in a new replacement.
 
I don't see any rot in any of the channels. I appreciate the feedback above and will take all into consideration.
