    I’m looking for a plastic glue something that can handle an automotive headlight mounting tab that cracked. Actually it separated. Poking around on the internet I saw there are some very specific types so I’m looking to see if anyone here has personal experience

    If its plastic and you don’t need to see through it, nothing better than JB weld for rugged

    If finesse is needed in a more crazy glue application (like kids toys) the gorilla super glue is great

    Plastic welding maybe? I have welded plastic together with a soldering iron and used a zip tie for a filler like tig welding.

    I was thinking of JB Weld and I heard some people have used a soldering iron as well.

    I have used Gorilla glue epoxy to repair lots of plastic, ceramic, and even glass. I would give it a try before j b weld.

    I’d use an epoxy meant for plastics. Last time I tried to fix plastic with regular JB weld, it didn’t hold.

    My very first thought was gorilla glue but after digging around I read that there are some real good epoxys with out the waiting of clamp time

    Yup, that’s what I would use. I once fixed the thermostat housing on my car with that stuff.

    I tried to glue my headlight mounting tab back together but with all the movement in a car I don’t know what would hold. I just ordered a new set of headlights.

    There are some 2 part epoxies made especially for plastic that work well. Loctite makes one that works well and can be found at your big box auto parts stores.

    From what I hear can withstand this kind of tension. I bet I could find this conversation on many auto forums.

    Ok……I being an outstanding family member…….decided to replace the damaged headlight for my sis. She bumped the front quarter panel and broke the light. Hood is fine.

    Found one in great shape at the junk yard….re aligned the whole quarter panel and bumper brackets to get it to reach the mounting tabs. I used ratching straps to my truck to pull in a few areas at the same time plus some persuasion. After it was all set I was being anal and decided to press it a bit more after installed and cracked the dam tab.

    Right on Bill, we usually use the loctite products here,

    Some plastics are very difficult to repair, you basically need a glue that will basically melt the plastics back together,

    You can try the method from @austin, that’s a good way to bond the plastic together.

    JB weld is too brittle to work with plastic unless it doesn’t flex. Use those come in a two part syringe works better.

    Oh no……….. I like to use two part epoxy over any glue, I’ve never had good luck with Gorilla glue and super glue just plain sucks. JB weld works good but not sure on plastic, There’s another product I like called MarineTex. It’s a lot like JB weld, I’ve had good luck with that too.

    Gee, might be a good time for you to try and let us know about that new stuff ya see on tv all the time. The one that cures instantly with an included UV light, It’s also the one that claims to hold a frayed cable together to winch a truck up on a trailer Hahahaha. I don’t believe that of course but I am curious how it is for some other light duty stuff like you need

    I fixed the brand new led tail light on my boat trailer with some cheap super glue. I hit something with it and split it open. So far it is still holding great and has been under water several times now.
    I have also seen a glue advertised on tv that uses a light to cure it.
    Looked like good stuff but haven’t tried it.
