    I'm not sure what that is on the rear of the window. The front clip doesn't have any of that stuff. In that area, where that one clip is, it has a very uneven surface that is rock hard. I tried using a scraper to get it off, but it's hard as the glass it's on. Last time I just sanded the area well and applied JB Weld. The JB Weld held until I tried rolling the window down one morning when the ice was apparently stronger than a typical thin coating (had to roll down to see anything - scraping ice off wasn't enough). The window motors just ripped the clips off. I'll grab a picture of the spot next time I have the window out. For all I know, someone could have applied something to that area of the window long before I got the car.

    My passenger side doesn't have that rock-solid stuff on it either. That one's also not the original door though.

    Looks like silicone on top of silicone. Always fails when you don't have good cleanup. I'm not telling you what to do in your shop, Tom, what I'm saying is what we do in mine and how well it works for us. But this looks like something that was BOUND to fail. Clear silicone, probably the original 25 year old stuff, with black RTV around it. By the look of it, I can't be sure if it was pulled loose of the clear stuff or the black stuff. it it was the black stuff, the tabs were probably in the wrong place. But she's your baby, you take care of it whichever way works best for you.

    Looks like I may have my foot in my mouth, I've just noticed that the tabs I glue on with Black RTV are made from steel, while these are made from plastic. I don't know if that makes the difference, but if it does, I'll eat my crow.

    Oh, duh. I was viewing this thread earlier in the day without pictures being loaded (slow internet). I see that now

    I wouldn't think so. As long as it's applied properly, and in sufficient quantity, the clip material shouldn't matter THAT much.

    Tom, you may want to rethink your repair, because I agree with it. lol. Plastic = bad. silicone on glass = bad. Surface area = good. However, the failed repair you posted just was not a fair comparison. It was just plain shoddy work. Clear silicone has no business being in any automotive repair.

    Sort it out, because I don't know who here believes you, but you're having a detrimental effect on their knowledge. By these examples, everybody else knows the difference.
    I can't say for certain what the original adhesive was, but it was a clear silicone of some type. and as you can see every time the original bond failed, it failed at the plastic, because it's almost always still stuck tightly to the glass in a nice molded shape of the inside of the clip. Clearly, plastic is the materials problem.

    I think what Tom is saying (and I could be wrong) when bonding "these two" surfaces together , when fluid or sensors don't come into play , it doesn't matter which color you use it isn't going to work ...or hasn't in his experience ... I have had that same experience of silicone not bonding well to glass.

    Of course I could be wrong, but that's how I understood him.

    If that's his point, I missed it. In any case, I think the material problem is the plastic clips, not the adhesive (although the choice of adhesive is important).
