[chriz1]

Headlight fixing tab that's starting to come away from the headlight what's best glue to use to strengthen this tab I think it's ABS plastic ?

Thanks chris

I tend to use Araldite for plastics that I want to stay stuck. Not the rapid the 24hr stuff, it helps if you can gently clamp it if not tape it while it cures.

[chriz1]

Which one do you use? As I was under the impression it doesn't work to bond plastics?

[OldBuoy]

I use Araldite Std. Just read the packet, it bonds most plastics except polyethylene, polypopylene and teflon. Just fixed some awkward seat trim that is under tension seems to work fine.

Cool will take a look

You want a solvent cement. MEK (methyl ethyl ketone) will do it (if you can find any), or if you need gap-filling use a solvent cement for plastic plumbing.

Yes tried solvent cement didn't help, just peeled right off when dry, so going to drop it off to local body shop to have it plastic welded proper

Q bond with the reinforcing powder is th stuff you need.

Used Bondloc B3294 a few times to glue "hard plastics" where superglue etc had previously failed. Excellent stuff and ideal for what you want to do. I glued a broken headlight tab on my car a couple of years ago and its still holding just fine.

On offer too!

Q Bond and powder is good, but if you have time and an old part or a piece of ABS, then chop it into small bits and stick it in a glass jar with some Toluene and let it dissolve. Once dissolved then paint it over the cracks and let it set. If you have some material you can also make gussets or brace parts and stick them with the goo you mixed up. It will bend and form easily if you use a heat gun on it so you can make patches to any shape.
It takes time to dissolve the pieces and also for it to fully set, but it works well as a cement.

If MEK didn't dissolve it, it's not ABS.

MEK is a cleaner not a solvent cement

You can weld ABS with ABS weld rod and a hot air gun

That's how they repair cracked bumpers

You can also make the join you have stronger by carefully melting at the join with a soldering iron, to force some hot material into the join while holding in place

Cools and hardens in seconds

I've tried 3 different glues to try and fix my fridge internal door shelf... Can't find anything that bloody works!

If it's clear and plastic it's either Perspex or polycarbonate

Again heat will bond maybe try the soldering iron trick if it just cracked

Might not be pretty

Could also be SAN or MABS. Quite a few other transparent polymers these days.

Agree on the soldering iron though!
