Removed the Fr. RH door panel to replace the 'carrier' and as I look at the back of the panel, it looks like at least some of the round push in clips are actually attached to the holes in fixings that are on a small curved plastic base (about 2" sq.) that is glued to the back of the panel, rather than the holes being actually part of the door panel itself. Well that's BMW I guess, but the problem is that one of these small mountings has come off the door panel and so cannot be used 'as is'. Therefore now either the panel will be loose at the front where that clip used to be, or, I need to glue this mounting back onto the door panel.

I'm guessing I'm not the first to experience this, so what is the recommended glue to use to firmly re-attach the mounting to the door panel. BMW seemed to use a fairly rigid yellow glue. Any idea what that is? Can it be obtained? Otherwise, what else? It has to be strong and withstand any pulling on the panel to undo the clip when the panel has to be removed. What's the best glue to use?
