    yes, you heard right! What is an effective adhesive suitable for gluing thick plastic to the metal frame underneath a car? Long story and I'm too lazy to draw a picture, but basically I mean the thick plastic "road debris guard" most cars have attached to the frame covering a significant portion of the car's engine and driveshaft and whatnot. The guard is bolted on securely but there is one spot that hangs down a little lower than the rest and it sometimes bumps on railroad tracks, uneven road surfaces etc.

    Anyway if anyone can recommend a good strong durable adhesive for bonging plastic to metal please let me know - thanks in advance (because I know wordforge has a vast array of talents on display).

    You don't want something permanent, because if they have to remove the panel it'll be a bitch to deal with and you might have to replace the entire panel. I'd suggest something like Gorilla's double-sided tape. I haven't used it, but I've used other stuff that they make, and it holds very well. Even if you have to replace it every couple of months, that's better than bonding the panel to the underside of the car.

    If there's an opening in that guard/cover, zip-tie it to someplace secure. That way if it needs to be removed for servicing, all the mechanic would have to do would be to cut the zip tie.

    Our fleet maintenance guy had to do something similar to the air dam/protector thing under my work vehicle.

    yes that makes sense! I'll get some gorilla tape at home depot or even check out an auto parts store that's on the way home - they may have it there.

    no holes or slats or anything I can get leverage on to zip-tie it. I have zip-ties and that was the first thing I checked for. It's really annoying because there are bolts every couple of feet or so securing this big one piece guard, except one place where the plastic sags down just a bit. Of course over time it sags even lower. :brood:

    It might be worth it to drill a hole for a zip tie. If there's nothing close by to anchor it, you can always string together a bunch of zip ties to get enough reach.

    I was thinking about doing that but nothing is close enough to zip-tie the plastic to. I could drill a hole in the plastic and in the metal above the plastic but I can't be sure that something important isn't behind the metal! :shock: Not worth the risk unless I can get a warm fuzzy about what I might be drilling into.
