Gorilla Glue is available from Bunnings and other hardware stores.  Or Gorilla Grip construction adhesive.

 

Yes they expand and foam to make a good strong fillet.  Tack the part tight in place first, then glue around if you are concerned about glue getting inside the assembly. 

 

You can trim surplus foam with a knife and sand if required. Don't buy too much as can go off on the shelf, if air or moisture get into it.

Pick-a-part? Usually the best solution is to replace the part. You could try welding (melting) it back together, sometimes works well.

Holdfast Gorilla Glue, a liquid expanding Polyurethane



It's probably OK in this situation (assuming it can bond the plastic), but be careful with this stuff for general use if you're gluing anything that's not hidden out of sight, you're going to get yellow-brown polyurethane foam swelling out where you've glued it. For my go-to adhesive I prefer Uhu, glues almost anything and dries clear. Plus you can use it as either standard or contact adhesive if you need that.


Just be aware that the Gorilla Glue type products only have strength in the contact area, there is no strength in the foam.

Likely a two part epoxy would be best. I glued a wing mirror back on with one of these products and it has lasted many years despite the stresses involved.

Following up to my earlier message, the Daiso glue I got does a fine job of gluing PE and PP, I haven't tried to pull it apart with max strength but it's holding up to pretty firm attempts to separate the two parts. This is the only single-component glue I'm aware of that will do this, everything else is two-component, either an epoxy like JB Weld or an activator + glue like Selleys. And it cost three dollars, a fraction of what any others cost.

Thanks all, upon further inspection, the part is not gluable, it's missing a few bits, so will take to the Toyota dealer to see if they can get a new part.

I learnt a lot about epoxy, various epoxy fillers ( for either adhesiveness or fillability), different fibreglass types, when I was restoring a plywood boat.

 

As well as paints.

 

Epoxy + fillers can be used to fix / restore many things.

 

I used West System epoxy.

 

They have a regular news letter that covers restoration, repairs, etc of art works, vintage items, etc etc.

 

 





My thoughts are no longer my own and is probably representative of our media-controlled government
