Default weatherstrip and RTV?

Would RTV work as a filler in a crack in the foam weatherstripping on the top where the windows meet it? Will RTV stick to the weather stripping?

I have a few small spots touched up with black RTV on mine, it works well and is lasting several years now.

It's been a long time ago,on a different car, but... seems like I lightly masking-taped a piece of wax-paper over the RTV, over night, and It gave it a real smooth finish. The color was slightly off though.

The wax paper is a good idea and would have prevented my current gooey-weatherstrip appearence if I had used it when I covered it in RTV/silicone; however, the fact is RTV is shiny and weatherstrip is not, so you will have a very noticeable flaw that the eyes will be drawn to. Weatherstrip should not be noticeable. Needless to say mine looks terrible now, even worse than it did when it was shredded, because at least it wasn't reflective and super noticeable back then.

I wish I read this before I used it. The crack was terrible to look at and I'll see what happens after it cures.

I used clear, it said it was for aqauriums. It did not hold that shinny look for long.

If it's to shiney, dull it with some scotch brite pad. It is tough to get smooth. I wear throw away gloves and smooth it down that way, I find it easier then using a tool like a flat piece of cardboard to swipe it on. I can't remember what else those scotch brite pads are called. They can dull glossy paint to paint in better to.

Mine looks like ***, because I did not even flatten it down at all. I assumed I would be able to shape silicone after it dried... wrong. So it's time to do what I should have done first, buy new GM weatherstrip. Hopefully I'll be able to extract the piece I epoxied on because it kept flopping.

This is weather stripping on a removable hardtop. Does anybody sell that?

Is that official GM weatherstrip they're selling or some aftermarket brand?

I can tell you what not to use - Goop! Someone here once recommended it and I patched a spot on my B-pillar with it. It dried rock hard and clear.

saran wrap works too. Just make sure when you close the area up (door, targa top, wahtever is touching it) that the saran wrap doesnt fold into the silicon.

Well, I used the black TRV and it works so far. It looks much better that that big crack. Color isn't too bad. Sure, if you go looking for it you'll see it.

I used black RTV a few years ago and it has held up well. My only beef is that I didn't think of the wax paper trick, and my plan to trim it flush with a razor blade didn't work out. Still, it's hardly noticeable.

Looks are secondary at this point, anyway. If there's a crack, that's an appearance issue too. What I want is to be able to use my original weatherstrip for as long as possible, since it still works pretty well. Replacing it seems like a huge PIA.

What about black liquid electric tape? I thought I remember someone having some decent success with that stuff. Maybe I should try some. I have the stuff just lying around....

I just replaced all of the weatherstripping in my '92 vert. After shopping around, this place was the cheapest and they have a good return policy:

One of the things that makes a car look old is dried up and cracked weatherstripping, I guess because it's the last thing people replace. Luckily there are many places that offer kits for vettes. Most of the work was in removing the old adhesive, but I'm glad I did it.

Yes. I've done it. In fact, GE makes an RTV sealant especially FOR this application.
